Motivation?

I have no motivation. But there are several factors contributing to that. What is interesting to me is that I am not motivated to help myself because there are other people who are worst off than I am. Am I wrong for feeling that way? Why is it that I place myself last when it comes to help. When I fell victim to a sexual assault, I decided not to press charges because of my concern for other people who could be effected (like his wife and children). I didn't want to take attention from other victims who experienced far worst than what I did. I didn't want to contribute to a growing docket in a crime infested city. And now, all I see are other people who need money, clothes and food more than I do. I don't know what is wrong with me but for some reason I refuse to help myself. The last thing my therapist told me to do was to learn to take care of me. But when motivation is lacking, what do you do?
