Just kind of an update

Things have been weird for me lately. I feel out of it all the time after starting Wellbutrin and have intense mood swings. I'm struggling with my weight immensely. My twin sister just got gastric sleeve and she's already 40lbs thinner. I feel as if everyone will look at her and then me and wonder why I'm such a tub of lard. My boyfriend is into bigger women so I feel like if I lose weight without telling him, I'll be betraying him somehow. I don't want to tell him if I do it because I don't want him to be upset. He would totally understand if I wanted to....so maybe I'm making up excuses for myself so I don't have to do it. It's not like I have motivation, anyway. I woke up today with my illness Cyclic Vomiting Syndrome due to the stress of finals. Finals week is the absolute worst. I'm cracking under pressure. I cut ties with my ex therapist. She made me uncomfortable. I plan on going back probably with a new one but not until this hell week is over. 
I also have a job interview next wednesday and I'm extremely nervous. It's a job at a summer camp working with children. I have no experience with kids but I like them a lot. I'm scared though. What if I get it and the kids hate me and judge me? I'm scared.
But before I can worry about that, I have to focus on academics so back to writing my physics research paper I go.
