Rubyetc is an illustrator who draws comical drawings that usually address issues of depression. She suffers from depression herself and is very open about it and uses her drawings to express her feelings and visually represent some of the things she goes through!
Others on tumblr feel empithized with her work and she has a huge following. It is nice to see the quite dark issues discussed and shown in a comical way. Making them feel less overwhelming and personal. I don't have depression but i can relate to some of her drawings and they make me feel good about times when i do feel down.
