I was diagnosed with depression and anxiety in my early teens and, years later with OCD. Best described as "not having a good time™".
I've always liked cute medical themed aesthetics. When I first found menhera I was initially happy there was a name for this specific branch of "sickly-kawaii" because I liked expressing my illness in cute ways, but always felt kind of weird doing so. It makes me feel, I guess "unified" and not alone.
And I like the themes of raising awareness and saying that you can be unwell, but you can also be cute-that your illness does not define you with sterotypes.
I also... just think it looks good.
I gravitate to syringes because I've had too many blood tests to try and figure out if I'm dying, anemic or just depressed.
