Stay with it Charlie. You have to set priorities, and that is your mental health. Make time for yourself and do some of the things you know will make you happier. Put it down in your appointment book and do it.
Have some fun, and find some ways to enjoy life, even the calendar sounds great! When I do not have much money to spend, I still do the same things, but spend a lot less. One of the things I found interesting recently is shopping the used stores. It is so surprising what can be found and enjoyed.
Just open your appointment book and start jotting in time slots. It makes the day seem so much happier!
Best Wishes,
