Anyone has or thought about applying for dissabilty?

I worked all thru my lumpectomy, chemo and radiation of course taking necessary days here and there as needed, plus it was a very small office and I was lucky to have had a great woman boss who has become one of my best friends so the actual job was very easy. But a few months after I was done with the chemo and radiation in May of 2010 I was laid off of work on July 30 of 2010. Still being on Herceptin thru the End of September of 2010 and my many doc appts and the rest of the testing that still go on, I didnt even bother trying to find another job. Now its been about 8 months since I finished Herceptin, and financially I find myself starting to struggle, even with a working husband and getting unemployment, so having 2 kids still in school, one graduation HS and one going to middle school next year, I have found myself contemplating that its time I go back to work. But as many of you know, I have been struggling with severe joint bone pains for a long time now, to the point where my dr finally took me off of Femara and swithed me to another med, which I have not started yet. So my question is, has anyone since their ordeal with BC, applied for dissability or contemplated appling. My family and friends have told me many times I should apply. But should I? I know the process is gruelling and actually getting dissability is slim to none of a chance. Any thoughts?
