I know from experience you are not likely to read this and even less likely to act on whatever it is that I could possibly say. But I'll try, anyway.
Your number one goal right now should be to get professional help. If you have made loads of money and still have savings, medical care shouldn't be impossible to get, so do it.
From my own experience (I probably have something minor that's been undiagnosed for more than a decade now), it is almost impossible to do anything at all when you are in that state. Or, in my case, to do anything other than the absolute necessities (I am still able to work, barely).
In your case, your symptoms seem to be worse than mine by several orders of magnitude (I don't want to set the world on fire). If that's so, then professionals will be able to recognize them and help you.
And it really does help. You may or may not require medication. If you do, you may have to take them for a time, or may never get rid of them. In any case, they need a while to work (on the order of weeks) so, if prescribed, follow the treatment as is and don't stop.
If you have someone close to you who can help (family? friends?) then get them to help, no matter what. I know that sometimes minor things such as calling doctors and setting up appointments require more energy than what's available, so get someone else to do it for you - and drag you to the doctor's office if need be.
Once you get better and your thoughts clearer, then reevaluate your goals.
Oh, and try to reduce your news consumption. I find that they resonate too much with my brain when I am not feeling well.
Good luck, and take care.
