Here is a list of other memes I have found that relate to depression / SI / things you get hospitalized for!
Mental Illness Mouse
Self-Injury Shark (careful: triggering)
Fuck Yeah Bipolar Owl (reboot of above)
Clinically Depressed Koala (careful: triggering)
Emotionally Volatile Bear
Borderline Scorpion (careful: triggering)
Male Eating Disorder Magpie
Let me know if you find more (or run one yourself) and I will add it to the list!
