So sorry for your troubles. You're a good daughter looking out for your dad like that, but you do need to make time to care for yourself so you don't burn out. Which it sounds like you kind of are. Can you reduce hours at the 2nd job for a while just to get a breather? I know money is tight but all work and no play is hard on your mental health. You need to find a way to destress. Walks on your breaks, getting fresh air. Anything to help.
