What are the "immediate needs" you are referring to?

I have lived by myself most of my adult life, but the time i had to live with my mother, i actually did like it better. It gave me a roommate who had pretty much the habits as i did, no weird cooking smells, altho she did tend to burn the toast in the morning! (She later claimed she did it on purpose to set off the smoke alarm and get me out of bed! )

If you really are not going to be able to swing it financially (i.e., having your own apartment), then i wouldnt do it if i were you. My mother was pretty mean and unkind to me on a daily basis, and wanted ALL my disability money (she was a gambler and really favored my brother), so when i could, i got out to save myself.

You dont seem to be in that situation. Your family seems to be more reasonable and kinder to you. Dont jump out of the frying pan into the fire.
