I'm not sure on the ideas besides suggesting opening a Ko-fi (never used one so take my suggestion with salt)

Perhaps some quick cheaper ych, a bit messier but easier for you to do and possibly make some quick sales. A Kofi you can get donated to as well may help like Haribunawa said.

Meme YCHs something basic and incredibly simple. One of my other friends started doing YCHs of stuff. Cheap $15 drawings could possibly help.

Like for example I started drawing the "Lizard meme" and people wanted to pay money for it due to the essence of it.
Another friend does the blep emote animated and it was simple and effective too.
Memes sell like hot cakes.

What about a cheap but simple YCH tf sequence?

No idea what happened to you but a fiew things you can do would be:

-Simple/Short comission type at a somewhat reduced price
-Ych type of Art to quickly fill slots and easily work on
-set up a Kofi or patreon for donations if you didnt already

I got an alien-like character that might spice things up but im broke rn
