That one question "If you woke up tomorrow with 100 million dollars, what would you do to improve your life right now?" Is very powerful. My first response was "Pay off all my debt".
The second most powerful question is: "What else?"
What else would you do after your debts are paid?
What else would make you happy once you don't HAVE to work?
What else would you do now you are debt free and have the time you need to enjoy life?
What else fulfills you?
By the time I hit the 3rd/4th "What else?" I realised what I was actually needing. In my specific case it was a creative outlet that I had been neglecting for years. I would remind myself daily about that one goal and, thought it took me 3 weeks, I eventually managed to pull out my guitar and start playing again.
2 years later and I'm sucking at guitar daily and going for runs. I have remade connections with people I thought were lost and genuinely started enjoying the little bits of life I have made. Debt is still there and work is relentless, but my 30min with my guitar has become a grounding point where I can remind myself "Things will get better, incrementally. What else can I do to make the little things better?"
Apologies about the wall of text. Depression is the worst version of ourselves and I hope OP can get through it.
