I Feel So Alone...

Hey... I'm a guy, and I kinda feel pathetic, but it seems I can't talk to anyone ab my depression.. Its on and off, one day ill feel good, the next ill be down and sleep, eat less and sometimes even cry. It makes me feel weak. Theres this girl I was interested in, we always used to talk, even tho she had a boyfriend, we went to the movies and such, I went over to her house a few times to chill. But her and her boyfriend were on a break, and she said how much she missed him, even tho the relationship is unhealthy. I told her how I felt about her, and we've been talking a lot less lately.... She told me she needs time to figure stuff out, and she doesnt know how she feels ab me. She started having feelings for me, so she says, but idk.... I even apologized for telling her how I felt.... And how shes going through a lot now, and told her maybe she shouldnt deal with me for awhile... I think i'm in love with her, even tho ive know her only for a month and a half... I feel like I got too attached way too fast.... She always told me I was always there for her... And after the "break" she called me over and we cuddled all night.... Which was over a week ago.... Ever since then, it seems like shes pushing me back.... I have a hard time not thinking about it.... I feel like i've pushed her away by telling her how I felt, even though she told me she was happy that I told her..... Its killing me that I dont talk to her as much.... I feel so alone, I feel like i'm ready to move on, ive only been in one relationship which ended a few months ago.... It lasted 7 months, and the girl screwed me over. I dont think it has anything to do with my looks, people always say im cute and hott.... But idk.... It seems like i'm always alone, and I thought I had things going for me... And now this.... I'm not sure what to do... I feel so down all the time. I could use any advice.
