Struggling with Food and Mental Health

tw: food, bad mental health I don't know what's going on with me here lately. there are days that I just want to go no food all day and then there's others where I just over eat and over eat. And I thought that reaching out to my former roommate to explain how terrible she made my mental health and trying to come to an understanding would make me happy but she acted like it was all in my head and one of her friends came spamming me about how I was harassing her and to leave her alone. I didn't intend for my message to come off as a b**ch but she wanted to play the victim card. I was just tired of ex-roommate triggering my ptsd and acting all perfect like she does no harm and wanted to civilly talk. she just intimidated me until I finally decided to try and converse.
