Awkward Moments and Depression

Ugh. So I had a sleepover with one of my friends last night, and she has a crush on me. Why the hell does she have a crush on me?! I don't think I'm at all attractive, I don't know what she sees. Plus I have a girlfriend, who I love very very much. I miss her like crazyy, and I think she's losing feeling for me. It sucks. and I know I'm crazy and that she loves me lots, I just wish I knew what I could do to make her more affectionate. She is a lot of the time in person when it's just the 2 of us, but when we're around people she's not, even though she says she loves PDA. Urgh. I think if I was skinnier, everything would be better and fixed. I hate myself for eating. Blehh. :/
