I’m so torn😖

So I got off my period like four days ago. Usually that means no more raging bitch, but now it seems like everything is either pissing me off or making me really sad. At lunch, my group always sits a four table. Today three of us (me being the fourth) went to sit in the school store, leaving me alone without anyone to sit with. Then this guy who I’ve been talking with for about two weeks (and I really like him) gave his sweatshirt to this other girl who is like a total hoe. I just don’t know what to do at this point😭
