Bryce, I am going to be a bit harsh with you, but I hope you take it constructively and to heart.
Part of being a responsible adult is doing things we don't want to do. I am quite sure your mom does many things that she doesn't feel like or want to do, but she does because she has a responsibility to herself and her family. Feelings have absolutely nothing to do with this. You do things because you have a duty and responsibility. Feelings don't enter into it at all. You don't filter your actions through your feelings. You're 19, a young man. You're not a child. I was out on my own, had a few jobs, went to school full time, and I was married before I was 20. Your mom, seriously, she doesn't want to take care of an adult who does nothing around the house. If you are going to live with your mom, show her some love and appreciation, and some responsibility by helping her out around the house. If you are going to live under her roof, eat her food, use her water, her electricity, and so on, at the very least earn your right to it. Nobody likes a lopsided relationship where one gives and gives, and the other just takes. You need to put some balance back into the relationship and start giving. In fact, I would say, for all that she's done for you, you might consider doing a little extra. Perhaps it's time you took care of your mom.
