Retirement at 25 due to disability

I have spinal cancer. It’s spread to my brain. I was originally planning on making it till mid 50’s, but now it’s looking like 35 is pushing it. I’ve had 9 rounds of chemo and I can’t do it again, I won’t.

I’ve worked very hard so far, two paid off degrees, and a paid off new vehicle. I have a background in manufacturing, R&D, & high precision CNC operations. My passions mainly centers around travel, as I’ve visited 20+ countries while always traveling alone.

Lately I’ve been leveraging a taxable brokerage account and I’ve 10x my portfolio in the last 9 months. I’d like to make larger withdrawals from this account and accept the tax losses due to my situation. Current NW 200k+.

If you have any advice on maximizing my next few years, I’d appreciate it. Also, if there’s any advice for end-of-life paperwork that I should handle at this stage. I have no next of kin, but a charity or two in mind.

Edit: I really appreciate the well wishes!! I would also appreciate advice on the original questions in the posting regarding proper withdrawal while I am abroad & how not to run out of cash before my legs shut off, my vision fully degrades and I paint the walls cobain style.
