My body rejected my ex

Hello!! I was in a 9 month relationship with a very very toxic man. My body rejected him from the very start but he didn’t show his true colours until later like they always do. I have no clue why i stayed for so long. Anyway, my hair got thinner, I gained weight, I lost my period, my appearance got worse, brittle nails etc. Just so many health problems around this man. We’ve been over for about 2 months now and my period came back but i’m still struggling with the other symptoms. I have always been a thinner girl. I’m worried i’m stuck with these issues forever. Will I ever go back to my normal self. I miss my hair.
