Glad I could help a little bit.

If you are a caregiver for your mother, maybe there are additional monthly payments you can request from the state or social security?

Alternatively, perhaps it would be better for you, if you'll get a professional caregiver, who will be paid by social security, and you can get a job? I don't know the rules in your country, but almost always there are more options than most people know.  There should also be some support hotline from the state which can help or at least consult for your options?

You could also look out for some local self-help groups that have similar problems and can give you some emotional support. I know those situations can be very hard, and I tend to try to solve everything for myself, but sometimes other people can give you a different perspective.

If I were you, I would get your finances in order and get some every daytime structure in your life. Your decisions don't have to be perfect every day. Just try to get more things right than wrong. In the long time, you'll get out of it eventually. And you'll get more options.
 

Just some remarks about your latest email.

I followed you because I liked the graphic style. I didn't have the opportunity to play your games much, because of IRL stuff. So I procrastinated gaming a lot.

Game development is especially hard in a recession like the one we are having right now. And it's, in general, highly competitive.

That said, I recommend you'll get a (part time?) daytime job to fill your monthly expenses. No reason to get into debt for a 'dream'.

And you can work on your future games in your spare time. So you have less stress and financial security. No reason to get a burn-out by working inhumane working hours.

The book 'So good they can't ignore you' from Cal Newport was an eye-opener for me. It explains the difference between 'passionate work'  and sustainable work in the long run.

If you want more possible customers, you have to get frequent feedback and have to think very hard, what the people want. Almost no game or book or movie was an instant hit on the go. There were countless incremental improvements.

Of course, if you want to stop developing completely, it would be fine, too. You can 'heal' yourself and look what you'll do in the future.

It would be fun if a network play against other players would be possible.
