Hi and welcome to PC (sorry I didn't see you come in

)
No one can please everyone. If you do, something is wrong. imo.
Your helping others is admirable! Now if you can learn to channel that energy and ability into pure altruistic motives, you will feel even better about yourself, and others won't be questioning your motives either.
The step daughter can use help, I'm sure. Make sure that you help her find ways to take care of herself. If you manage to help others learn self sufficiency while you give them support, you will be a top citizen, imo.
Often, psychologically, ppl demand they please others because of their own feelings of inferiority. You have some pretty good friends there, who are comfortable telling you what they think. I wonder if your efforts are making them uncomfortable?
((hugs))) Thinking about these things can be good for us!
