I know how it feels to have dreams you've worked towards get further away through no fault of your own.
The only advice i can give although it maybe of little comfort is to find a work around. Maybe teach yourself to do rudimentary sketches with your other hand to lessen the strain. Or work out how much work you can do a day and time comissions accordingly, people will wait if they know it's so you can work safely.
Also correct me if I'm wrong but isnt RSI treatable? If so with some effort you won't have to start from square one which we can agree would be preferable.

As far as I’m aware, the treatments for RSI are all kind of short term fixes. There is anti inflamitry medication they can give you, or physiotherapy, stretches. All things that can aliviate, but not cure. There is surgical correction too but that only seems to be for more serious conditions like carpel tunnel syndrome. And so the treatments will only work so long as I’m not putting further strain on the arm. Which means bigger brakes between drawing sessions and avoiding all the heavy lifting heh. That’s as far as I know anyway. Still need to make time for the doctor to tell the best way forward. I’m just bad at mustering motorvation to do it because all of my silly hang ups about seeing the doctors.

So, I don’t know. Yes, there are ways forward. And it’s not all doom and gloom... I just sometimes feel like the walls are falling in on me and I can’t imagine my self past the rubble of their ruination.

Thank you though, for your support. I do appreciate it greatly.

You're welcome and maybe you cant pull yourself from the rubble but all the people who support you can

I hope you saw a doctor in the end!

Unfortunately I’ve not. Since writing this things have just kept getting more hectic at work and I usually take my days off to catch up on sleep. Plus getting to see a doctor around here is a mission in of itself, despite my not really wanting to go. Thank you though, for your concern. :)

Oh no! o: If your condition is persisting or worsening, I'd still recommend trying to see one!
