Believe me or not, but I lived the same way until not long ago. I had nothing to believe in and felt that my life has no value. And dont say that you are the 'only loser'. Its not true. No one is perfect, and that is fine, there is nothing bad in it. Just accept yourself the way you are. Dont do anything that will prove your weakness-I mean, no matter how bad life seems to be, one day you will realize that it is not that bad. For me it helps to think about ppl who have lives worse than mine.
Its funny, but not long ago I was complainin all the time about how lonely i feel,too, and how much i want to give my love to someone.
I hope you will be ok soon. If you have something on your mind, u can always share with me,ok? I would really appreciate it...

Take care babe
