I can relate to quite a lot of this. It's not easy, being an artist, especially when direct family is unsupportive or dismissive of your passions. It's easy to lose sight of the things that you have accomplished and feeling like you're not contributing much.
I saw your gallery though! It's filled with so many works, all proof of your efforts. The improvement is more than clear to me when I compare the first few pieces to the more recent ones. As a fellow artist, with similar struggles, I think it's really inspiring. You've been creating things despite all this adversity, with multiple projects here on itch!
I think it's awesome, and I'm not saying that just to make you feel better either!
