I'm a big fan of Medibang Paint Pro, they have a huge library of brushes uploaded by other artists as well as ways to make custom ones! I also just happen to like their brush selection in general lol

Sounds like a really nuanced situation that I don't feel entirely qualified to speak to, but I don't think you're crazy for being upset about what was said and done to you, especially when housing is at stake.

Mmm hemi action
