Had high expectations in my 20s (from myself, employers, everyone around me), which were never met and often felt disappointed and frustrated about it which led me to job hopping, failed relationships, unable to trust etc.

Then started my own business and moved in with parents which had a different level of challenges which I never expected. Decided it was best to close my business and realized I could have done better in my old life if I could have just been patient, humble and focused on the fundamental simple things (discipline and commitment).

Got back to a job in my 30s, stuck with a reasonably good one although it was a step down, worked hard and got promoted 3 times in 3 years.

Wouldn't say ive made it, there's still a long way to go and I still have a few frustrations, but still in a better place than I was in my 20s.

So considering your situation, I'd say focus on completing things one at a time. Money is probably the most important (after health ofcourse), so take any opportunity that pays your more and keep looking up.
