Have you explored options to tap into the equity in your house? With the recent real estate boom, I am assuming your house is worth a lot more than your mortgage, so there are probably potential options to tap into it without selling your house.
I understand you are busy, but if you are feeling overwhelmed and depressed, I would highly recommend getting at least some professional help. Your mental health is important and needs to be prioritized. Hang in there - you got this!
