I find that the main reason things like art are hard is to do with the lack of support from others, it's hard to get motivated when there's no one to cheer you on. And sometimes the internet just doesn't cut it.
I always say do stuff as long as it gives you fun. I started writing my stories and publishing them, bc I always had tons of fun just thinking about potential developments and perhaps someone will actually enjoy them someday. I really think you have a very nice drawing style from what I've seen yesterday. But well, it's not like me saying that will magically help you feel insanely better. Just know I really like it.
