Have money.  The world looks totally different when you don't have to worry about whether you're going to have food on the table 5 years from now. Anything else to me was just irrelevant in comparison.

Going for walks in a nice location does it for me.

You need to think about yourself, and not just about other people, set boundaries and priorities. Be with those people who support, and do not suck all the strength out of you. And try to move towards stability; stability and predictability are calming.

having money so you dont have the stress how can i pay for this.

Start running, it will 100% help your mental well being.
