Sir view my response in the "Simple Question" thread, I believe it could do you some good also. I was going to post the link but I don't have five legitimate posts yet so meh.
Also I think it is safe to assume that you are young, probably a teenager, no? 14 to 16 perhaps? I could be wrong about the exact number but that is not important.
What is important is that you realize that mentally you have a lot of growth left, both on a physical and psychological level, and that while the next few years will be exceedingly difficult you don't give up hope, and don't lose faith in humanity in the process. I know I'm about to sound like an old man but I'm 20 so at least take what I have to say in consideration...
Life is crazy, and life is difficult. Especially in the teenage years. Your hormones haven't stabilized yet and until they do you are going to feel emotions at an excessive level. That does not make the emotions you feel any less genuine, in fact what I've just said validates that you are definitely feeling the things you are expressing here. The message I am trying to convey however, is that these feelings ARE temporary and that with patience and determination you will get through them and you will find what you're looking for if you give it time, and work at it as well.
