I am a softy...

Yes I am. I got so many times disappointed in people, I was let down by others I helped them so many time, I never and I mean never got back anything in return (do not mean materialistically). I still did not learned my lesson. I still give, and like giving more then receiving. Love the expression on people's faces when they receive, the surprise, the emotions.
I am old enough so I am giving up the idea of changing myself. I just will stay the way I am, and will take further disappointments for helping others.
My last help was: I took in a girl with drug history from the street. I straggled with her psychoses and side effects from her withdrawal.for 3 years. I gave her shelter, food, helped her get medical help, with my friend find her a job, encouraged her and supported to get education.
After 3 years when she was settled, she moved out and slowly she just deleted me from her life. Now she doesn't even know me. Her mother died when she was young and she kept saying I am her mum now, which I did not encourage because you can have only one mum in your life.
Anyway. She is gone 
It was not a first time I helped someone like that. And they all just forgot about it. Is it me or is it people just in general?!
