Hellion,
It does get very tiring and depressing just sitting around and waiting to be approved for SSI. I think that volunteering some time to a cause close to your heart and within your abilities will help the time pass a bit faster.
SSI is a relief, yes. But, the income is considered to be extremely low. Income is closely monitored throughout, so you aren't going on vacations and "living high on the hog". County assistance is generally still a necessity to help buy groceries, to make it through these long months. There are also meal charities ~ some are more fruitful than others.
I'm not trying to scare you. I just want you to understand that when a person is approved for SSI, things aren't much easier. Some aspects are easier, thankfully! But lots of pain in the rump complications pop up with government assistance as well. Re-applying for assistance year after year with the county, and apartment building, seeing your local social worker every 6-12 months to renew their paperwork, etc. {In case you hadn't noticed, I abhor all of the freaking paperwork!}
But, you do what you have to do. Just wanted you to have realistic expectations, Hellion. Gentle hugs to you.
