I don't think so.
I used to be very poor, every month was a struggle. My income increased a bit to where I know everything I need is taken care of.
I didn't work before, I still can't work. I didn't have friends or a significant other, I still don't. I still have anxiety, depression and psychosis. So my day to day is the same and my MH issues are the same. My anxiety levels are about the same oddly, I just freak out over made up stuff now. If my income went up 10x or 100x or more I don't think anything would change.
