I. In a similar situation, I have sarcoidosis, and arthritis, and in flare ups I can be bed bound.
Because the disease has no predictability, I can be fine for a while and suddenly not.
It makes it extremely difficult to be able to commit to a schedule.
I found I really enjoyed going to the beach when I was physically well enough. In time I started collecting driftwood and sea glass and bringing it home.
I ended up making a few projects, and people liked them, so I gave them as gifts.
Then people asked would I make something for them too, if they paid me.
It grew from there.
On days I feel ok, I go to the beach and gather. I can go as slow as I need, and take breaks as I choose. I also photograph the glass at the shore
On days when I have small bit of energy, I make art.
On days I can't move and sleep most of the time, I lay in bed and do photo cropping, make albums and order prints, do emails , and post ads
Doing it this way gives me the chance to work as I am able, and still brings in a few bucks, without the obligation of a paid position.
I don't have to worry if I wake up sick that I am letting someone down. If I wake up feeling well enough, I can go to the beach, and know I am still being productive!
I know it's not an option for everyone, clearly, but maybe there is an idea like it, you could do, based on what is in your area?
