My wife is a people pleaser, my advice (if you want it) is dont expect anything in return. She does so much for others, and then doesnt get reciprocation and it really weighs on her heart and mind. But, if you do something nice for others and dont expect anything in return, you can just count that as a jewel in your crown :) dont label yourself a burden, that takes away from your self worth, and you are worth quite a bit! You just gotta find that worth in yourself and embrace it, own it, even show others...that is called confidence, and you are able to have it even if you feel you wont ever achieve it. Its possible, trust me. Boma is right as well, as you age things will become easier, but every challenge you face along the way is an opportunity for you to become stronger, more confident, self reliant, and you will develop a can-do sense of "adulting", hang in there! And stop that being down on yourself.
