I feel i want to give up

Sometimes,I try so hard to talk this situation im in out. I even meet ppl half way, I'll admit if I think I could be wrong in places and although im not been perfect , I do t see myself as a threat to ppl. If ppl could feel what I feel about life they'd know I dont like seeing g ppl hurt or even think of me hurting  someone. But im begins g to realize, nobody cares. Ppl think what they think and I can't change it. I have no fight left in me and there's no hope to make it right. Nobody believes in me.....so I think sometimes, maybe it be best if I just quit trying and go away. End it. Its just a feeling  I have. And I don't know or don't think it'll get better. I use to think that being g kind to ppl was like.....what we are suppose to do...plus I lack ability to even fight back. Even when I want to its hard and as I got older I thought it was because im wiser, but maybe it's cause im actually weaker. I dont see an end and by time I actually do get chance to be heard, my life will be spent and what's the point at that time, I won't be able to improve my life then.
