I am living on a disability income of $900 per month. After a student loan garnishment and a Medicare B premium, I am living on $770.
I rent a room in a house for $650 per month. I am living on fumes and feel trapped: I cannot afford my current housing, but I also am unable to move somewhere cheaper because I am unable to save up the moving-in costs. Is there any hope for me?
Not knowing whether your disability is long term or short term will affect my answer to you. What are you doing with your free time? I can see that you have access to internet and are able to use a computer. Log on to Craigslist and search for a "part time job". I just ran a search in the Portland, OR area and found several that will accommodate you working from home. That is one way to increase your income in order to save enough to move into more affordable housing.
If your disability is long term and depending on how much your student loans are for, you might want to consider bankruptcy. If your condition is such that you will never be able to work again and have loans in the several tens of thousands of dollars there is a rare clause that will allow you to bankrupt student loans due to financial hardship. This is not an easy process. I do not suggest it unless your condition is such that you will never be able to earn more than your $900/mo.
