Hi
I know a couple or three people with MS and it isn't easy disease to live with.
I would look into house cleaning more for money. See my blog for more information too at

Look into your local freecycle.org and free section of craigslist.org for things for your daughter. She is young and it is more important you are able to keep food on the table, roof over your head etc. first. The vacations and all else will come later when times are better. And the two sites I mention a lot of people I know use them for clothes, games and more for their families.. Do check it out..I know about it being hard as I haven't been on a vacation in years and know many who haven't..
Take care and take it one day at a time.
