Sorry to hear about your loss. Losing a parent is very hard no matter what age you are. I am also caring for my elderly mother and my sick husband while working a full time stressful job. So I understand where you at Kayhm.
Sometimes it is hard to focus on one self when you have so many people depending on you to take care of them. But you have to find time to take of you. I take one night a week and go out with friends or just by myself for a while if it is no more than an hour it helps.
You can check this thread for some ideas and suggestions given to me when I was in a similar place as you.
