If I lived in America and if it weren't creepy I'd offer to have wheelchair races with you down the street that would have to cheer you up!
- oh and help you getting your wheelchair in and out of the car so you can go to the doctors of course (I have my priorities sorted!) :P
I'm sorry to hear how tough your situation is at the moment. My dad's job was made non-existant recently, but the company did it in a way where they won't have to pay anyone redundancies, which means we're very likely to lose the family home unless he can find a new job within 2 months or unless anyone else in the house can manage to find enough work between us to take over paying the mortgage.
I think the worst part is not knowing how things are going to go down... But at the end of the day, family is the most important thing and we'll stick it through together like I'm sure your family will by the sounds of it
As for being able to see a doctor... Are you on speaking terms with any of your neighbours? If you're able to drive, maybe a neighbour could help you put your wheelchair in the car and then you could call ahead so that someone at the clinic could come out and get the wheelchair out again for you?
PS. pets are the best, I have a giant lap dog (golden retriever) sitting on my feet right now with his head on my lap looking at me like "why aren't you patting me? What could be so important that you wouldn't love me?" :P he is very much a clingy, sooky, mama's boy lol
