How to stay sane and motivated

Due to a burnout I quit my job in August, I can't say I was mistreated but they were taking advantage of me.
Then I spiraled down, with anxiety, panic attacks etc. Went to therapy and now I feel better and also I'm looking for a job. I live in France and idk what's happening but finding a job is terrible. Overqualifed, or not enough experience, no replies... I apply for everything I see.

And I'm bored. I'm horribly bored. I struggle a lot financially, I have debts, my savings are gone, I see no perspective for me. I wake up, do stuff, and that's it. Everyday, staying at home, going out for a walk, being frustrated that I can't buy anything. I force myself to go out otherwise I'd stay rotting in bed. I keep doing art, sing, but for what ? I'm just here, trying to manage my bank account, my mental health and that's it. I have friends but they're often very busy so we can't go out, anyways why would I go out I can't afford a drink since I calculate absolutely everything in the month.

If there's anyone in this case, who were in this case ; How did you manage to stay sane and not fall into a depressive state ?
