my roommate attacked me, and now wants to go to mediation

Using a throw away because my main is known.

I have to keep this vague because my roommate uses reddit and I can't chance them finding this. I love Dusty's videos, and I'm hoping his small but dedicated following can give me some good advice.

My roommate attacked me. Police were called. I chose not to press charges because I thought it wouldn't happen again. I'm less sure now. My roommate keeps trying to get me to engage with them. I gave it an honest try. I told them that I'm very sick at the moment (extreme nausea, preventing me from eating. This has been going on since December 2024) and thus very vulnerable. If they try to hurt me again, I have no way to possibly stop them, or get away. I struggle to be upright very long. I asked them if they could imagine why I would be uncomfortable being in the same room as them at the moment.

My roommate's response was to start talking about all the ways I made them uncomfortable. Seeing this wasn't going to be productive, I tried to politely disengage and go back to my room. My roommate followed me, trying to get me to engage in an argument. They persisted in their attempts through my closed door.

This morning when I went to get some juice, sadly the only thing I'll be able to get in me today due to the stress, my roommate asked me for my information to give to the mediator. Surprised, I asked "What mediator?" my roommate gave me a disgusted look and said,

"The professional mediator. I need your information to give them."

"I'm already making plans to move out. Why would we see a mediator?"

They proceeded to ask me for my contact information again, and I ask "Isn't this the sort of thing I would need to agree to?" My roommate then proceeded to guess my information and inform me that we would be seeing a mediator.
I don't know what to do. I'm scared to talk to the mediator because I don't know anything about them. I don't know who this person is, or who they're affiliated with. I plan to ask the mediator directly, but I haven't been contacted yet.

The main thing that my roommate is upset about is that I won't 'talk' with them. They don't want to talk with me. This is why grey rocking doesn't work. They want me to sit there and listen while they tell me all the reasons I'm a bad person, and they're a sainted martyr. Being dull and unresponsive doesn't work, because what they want is for me to sit there and take it.

I don't currently have a safe place to go. I've got rental applications in places, my friends are doing a little fundraiser (not asking for money, I have that covered!), and I have plans to put locks on my bedroom door Monday. I live in Canada, if that helps. My roommate is a sibling. I've already called a domestic abuse line and they agree, my current plan is my best bet.

My problem is this: What do I do about the mediator, and what do I do if my roommate tries to engage me in another 'talk'? Walking away makes them mad, trying to sit through it makes them mad, engaging with them makes them mad. How much clearer can I say "You attacked me! I don't want to be in the same room as you!"?

Current plan is to tell the mediator that I was strong armed into going, and that I fear for my safety. But then I saw this article* saying mediators are often ineffective in domestic abuse cases, as they fail to notice domestic abuse. I think it would crush me to be dragged before a third party, and be told also by them that I was the bad one.

I know this is pretty heavy, and not really what this place is for. I just don't know where else to ask. I've seen a lot of Dusty's videos, and I've heard a lot of comments from the community. You all seem very kind. I'm so sorry to put this on you, but I don't know what to do. Any advice would be welcome.

I promise to explain myself properly, in full detail, once I'm safely moved out.

UPDATE 1/19/25 FOR PEOPLE WHO CAN'T READ: Canada. Caaaaaaanada. Really sick. No guns. No weapons. Already looking for an apartment. Live with abuser! Abuser be released after being arrested, hurt me again! This bad. BAD. Hope said this simple enough for you.

Update 1/19/25 for people who can read:

Thank you so much for your concern. I'm going to get a personal alarm, and see what my legal options are on Monday. My cat is now safely with my mother, meaning I can pick up and go if I need to. Small reminder, my mother is a hoarder and there is literally no place for me at her home. I have tried to contact our local domestic violence shelter, but they are surprisingly difficult to get a hold of. I'll keep trying. I have a couple potential options for places to stay in the short term, but I have to wait for people to get back to me. Will keep you guys posted.

Update 2 on 1/19/25:

Will know in a few hours if the domestic violence shelter has room for me. Will keep you guys updated.

Update 3 on 1/19/25:

No room at the DV shelter tonight. I'm going to see about my legal options in the morning.

Last update on 1/19/25:

A friend has stepped in and offered to loan me whatever money I need to get somewhere safe. It's too late to do anything tonight, so I'm going to see about my options in the morning. I want to leave off tonight telling you what I've been telling a lot of people today: the help that you offer IS help, and I am incredibly grateful for it. You've all helped me verify my reality, which is incredibly important when dealing with a gaslighter. I couldn't be sure if the way I was viewing the situation was correct before, because I was constantly being told I was wrong. I now know I'm not crazy thanks to you guy, that that is invaluable to me. Thank you. I love you all.

With any luck, I'll be somewhere safe in a day or two and I can give you guys the whole story. I'm looking forward to it, and to putting all this behind me. Talk to you guys in the morning.

Update 1/20/25:

I'm safe. My roommate and I talked, and we are going to give each other space. The plan is still to leave as quickly as possible. I'll check in occasionally to let you guys know I'm safe, but unless anything happens, the next time you guys hear from me will probably be when I'm out and can talk freely. Keep your fingers crossed!
