Wheeling with new wheels

Why should people with disabilities be hurt just cause they want to help others? When people are down on their luck they just need to come at situations from a different angle-- there's always ways to improve a little. I don't get how the answer is to take advantage of others. On the other hand, some people can really turn their lives around then once they do it's too late. Unfortunately, a life can improve but the trouble doesn't stop. I became friendly with someone who owes money and ran. Finally she turned her life around but the past found her. Why is it so hard for me to give up on people? Maybe it's because I can't give up on myself. Maybe it probably has to do with my disability
