I am also sorry to hear that you are having to live on only $807/month, as well as the medical difficulties. I am only in my 50's, but I have been ill for the past 3 1/2 years with MCS (Multiple Chemical Sensitivities) and severe Allergies. Having this has pretty much confined me to my home and I can not work out in public due to chemical smells such as perfume, paint, dust, cleaning chemicals, any construction type work, and the list goes on, and on.
For those of you that want to work, and are able to work, there are legitimate "work-from-home" companies. I have been doing this type of work for the past 3 years, and it has been a God send as far as gaining an income! All it requires, is high speed internet (which if you are on the computer right now and typing these posts, you probably already have it), a separate phone line to be used for work (my phone company dropped a line for $75, and it is a basic/no frills line, so it only costs about $30/month for the phone line. Some companies use USB headsets, so you don't have to have a separate phone line to take incoming calls!). The companies pay anywhere from $8/hour - $10/hour and they also pay you for training. Customer Service is what I do however there are a ton of different categories for work-at-home jobs. You could EARN an extra INCOME, and it would still meet the requirement of the $15,000/year extra income on top of the SSI payments, so you wouldn't be taxed on that unless you made more than they allow.
Just wanted to throw this in here, as a way to gain an extra income, working from the comfort of your own home. If you enjoy talking on the phone, helping people, and sitting down while you do it, then this would be perfect for you.
Here is a website of legitimate jobs working from home. I have been using this site for the past 3 years. (And no, I am not affiliated with any of these companies and am not advertising for them!) I simply found a solution to gaining an extra income from home, which has allowed me to be self sufficient, for which I am extremely grateful considering the health situation I am in. It makes me feel good that I will be able to continue to work from home when I begin to draw my Social Security, knowing I won't be "limited" to only the SSI each month.
