Trouble with life.. Please help?

So I've been very upset lately. I'm hanging sejak a thread emotionally. This guy I really like, and he likes me back, told me that he didn't want to be in any relationship this tahun and he doesn't want me to wait for him. He is a senior in highschool and I am a sophmore, and he berkata he won't be ready for a relationship until college (so he thinks). I get dumped on with homework every night sejak my teachers and stay up to almost midnight sometimes doing homework. I cry myself to sleep a lot and feel like I don't know who to go to. I'm not doing well with my school work no matter how much I try. I hate how I just feel so hurt and Lost and sad almost all the time and I don't know what to do. I'm really hurt and depressed about things and I just need Nasihat to carry on. Thanks
