My home is super cluttered, so much so I don't usually let people in. It's largely a result of depression, and unwillingness to get rid of stuff that used to belong to my wife. Funny thing is, at work I'm pretty tidy. I guess I'm able to section off a few hours each day during which I do my job, and focus my energies on those few hours, but after I get home, I go "kaput."
Re: disability, I'm glad it was pointed out that mental illness is a disability just as much as physical disabilities. My mother suffers from severe bipolar disorder. For many years she was undiagnosed, and therefore untreated, and it wrought havoc on her life. (Actually, it's amazing she did as well as she did, but that's because she's a great person!
) Once the doctors diagnosed her and found an effective treatment, she's done much, much better. But still, depression can be a very real challenge for her. Right now she is depressed, and that is affecting her ability to complete physical therapy after her accident. When she's depressed, she can't push herself as hard as necessary, and can't deal with the pain. So she is seeking ECT (electroshock) treatments, because those work really well for alleviating her depression.
My therapist (I have bipolar also, though not as severely as my mother) has cerebral palsy, and is confined to a wheelchair. At first I was a bit uncomfortable, but he put me at ease. He used to play wheelchair tennis, and his upper body is really BUILT! Interesting thing is, even though my illness is mental and his is physical, we've found that we have a lot in common when it comes to our emotional responses to our challenges, so using his experiences dealing with being in a wheelchair, he can help me deal with my mental illness.
