So I snapped at my teacher

So imagine yea Im going to my pe lesson today and I'm running on pure adrenaline and the fire alarm goes off and I've already had a bad week, (I haven't eaten properly, not sleeping properly. Like I literally went from. Eating 3 times a day to once a day) and I know myself, I know I'm stressed. My eye is twitching. I'm barely able to stay awake. I feel out of it. My legs keep moving. I keep scratching things. Picking at My nails. You get the gist but it was my eye twitching. And I was just yea I'm mega stressed.. I'm detouring. So let's get back to it right. I go outside and it's raining. Like full blown raining. And I said yea I'm done and when I come back in I'm texting my mum and dad cause I'm not staying, I got to reception tell them. And I yelled at this lady (the school nurse) cause someone had to have known about the fire alarm and she's acting like she didn't know and saying "you can't leave" It's not possible for someone not to know. You didn't tell nobody you were gonna do that during the week. Half the teachers looked confused, so in my mind. "I know someone pressed it" but instead your gonna make everything go outside get wet, and not even try to figure out who did it. Mind you second time this week this happened as well. and like now I'm home I feel bad but at the time I'm crying and I'm having a literally panic attack in their faces.

That's my today story I guess. Idk. I was actually gonna call the police if they didn't let me go cause I just needed to leave
