I am bi-polar. After positive changes in my life, I was living medication-free. During 2020, I resisted admitting to myself that I was horribly depressed because I didn't want it to be real. When I finally got back on an anti-depressant, I could have kicked my own ass for waiting so long. See a doctor now. Depression can be treated and you might not need the meds forever. Get help.
My bi-polar also causes sleep issues. I take a medication for that, too. You might need the same. But lest you think I think pills are the answer to all problems, first stop taking naps and try to get more exercise to help with sleep.
But see someone about your depression. There're solutions. Depression is the worst hell and it isn't required.
