My way to finance it was to quit both smoking habits.

It worked, for the first week....
after that I decided it was worth it and I shouldn't bother to much about it.

Then again, I'm the only one responsible for my own actions,
ok, I might hurt my cats' feeling in some way.

Which is no option for you,
but big props for handling your own disabled child.
To many people these days can't even handle their healthy child and need tv-shows to help them.
