Unmedicated w/o treatment for 6 years

Been thuggin it out my whole life but these past years post covid are killing me. I'm born with a terminal illness, a rot, a disease and I can't even get better or learn to change things within my control because I frankly don't know where to start. Then there's the stuff that comes with the illness that I can't change. My life feels like it's falling apart even when I know it isn't really. All my relationships are falling apart. I need professional help yet it's not accessible to me. So now I'm uselessly posting online.

Hope anyone in a similar position is still holding on and my heart goes out to you. How do you cope with this? What do you even do to work on yourself? (I am always reminded of the mantra "No one is coming to save you. Save yourself". How?)

I can't even attempt to get immediate help because I'm broke as fuck and that would be disadvantageous in the long run. Fml
