I can give you some anime about art and the struggles of art and writing and any creative endeavor. These ones inspired me a LOT when I was in my low point.
Sakurasou No Pet Na Kanojo is about a normal guy who gets thrown in a a dorm called Sakurasou, where all weird, chaotic art students are. In the middle of colorful cast involving a world-famous painter, a genius animator, a writer and a shut-in programmer, he remembers that he also had something he wanted to make. This series made me cry a lot because of how realistically it portrays failure.
Definitely recommended to EVERYONE here
Blue Period (read the manga the whole thing is about ART)
Bakuman (same as Blue Period)
A Sister's All You Need (this one helped me a lot with my novels despite it being WHACKY and WEIRD AF) if you wanna watch this one watch it in dub, and no matter what, don't close the first episode until the first five minutes passes
