<human>: This girl and I are going to the same school, and we had a few classes together. When I first met her I thought she was kind of pretty, but as we were around each other more at school I started developing feelings for her. At this point we were somewhat  friends and we had talked outside of schools little bit, but not too much. I thought that my best option would be to ask her out, because you miss 100% if the shots you Don't take right? So in one of the most nervous sentences of my life I asked her out. The following Monday after school she approached me and said that she wasn't ready for a relationship. I was slightly crushed, but I just reasoned that it was probably for the best. I don't think she had been in any relationships, and if she didn't feel like being in one now, of corse that's fine by me. I still felt strong feelings for her. Fast forward  just under 7 moths later, and I've tried to continue being better friends with her, and we have, but I don't think a day has past since where I haven't thought about her. Every night I think about her when I am falling asleep, and every morning after I wake up. Whenever I think about her I just want to be with her. Some nights I have trouble getting to sleep thinking about her, and I'm going crazy. I always hear people saying (not to me directly) that it's best just to let go, but I don't know how or if I could do that. I was talking to one of my friends [15 M] about this (I didn't open up quite so much) and he suggested I try asking her out again, but I don't want to be too pushy, nor would I even know how to frame the question. I just don't know what to do.

Give me the gist of the text in a nutshell
<bot>: I asked a girl out and was rejected. A few moths later I still can't stop thinking about her, and I'm going crazy. I don't know what to do.
