I feel like my mom is trying to live through me sometimes...?

Stop caring what she thinks and do what you want. If you feel like doing nothing, then do nothing. She will come, but don't let her give her opinion or make expressions and so on. She is trying to make you feel guilty or indebted. Find out what you like by spending more time away from her and doing what you like and encourage her to do things to make herself happy and not try to live through you.
