Well, this looks like my kind of place...
I've had depression and anxiety my entire life, and was actually diagnosed in early childhood with depression and with OCD. I was also diagnosed as Autistic as an adult, though it's the depression and anxiety that are the biggest problems in my life (and really, they're just parts of the tapestry as far as how my experience with Autism shapes my brainwaves). I'm medicated for those and recently changed my medication regime during a period of having regular panic attacks followed by stronger depression and anxiety than usual.
I currently volunteer on an irregular basis, speaking to educators and parents about autism and bullying and what their kids/students may be going through and how to best help them. Speaking publicly as myself is kind of scary and can be incredibly draining considering the nature of the topic and the kind of questions I have to answer, but I'm really motivated by the thought of sparing the current group of kids with ASD even a small amount of what I went through (I was undiagnosed when it came to autism as a child, so I went through the regular school system with IEP modifications for the OCD and anxiety).
I'm also in a program for adults with varying developmental disabilities, that provides classes in the arts and studio time, as well as having a relationship with a gallery where we're sometimes able to display/sell art. Most of the people there have cognitive disabilities, which is the one area I'm not affected personally, and a few have physical disabilities, but it's a program that caters to the underserved population of adults whose disabilities are not necessarily severe ones. Most of the disabled population is classified as 'mildly' disabled, and most of the services and day programs that exist are for the severely disabled. This one welcomes anyone, and it's been different to be part of the disabled community as a whole, instead of just the Autistic community, but it's been a great experience for me and the art being created there is really great.
