I'm in a need to file bankruptcy for financial reasons, is there any way to get help with that?

I was served by a deputy for an old debt which occurred before I was legally divorced from my husband in 8/2011 I have been on SSDI since 2003 and when I am healthy, work part-time at Walmart; I have been out on medical leave since 10/15/2014 because of open ulcers on my legs for which I currently go weekly to EMMA vascular/wound care once a week. My doctor does not want me on my feet as I am a cashier and I need to keep my legs up as much as possible with compression on them for them to heal correctly; correctly return to work date is 4/30/2015, but that could change depending on my healing at that time. Filing bankruptcy at this time would take a lot of stress off my financial pressures and would help to improve my health as I am on a medication currently for anxiety which causes me to break-out, and causes itches in my arms, and makes my face break out so much that it looks like more of a beet than a face. Also on a lot of medications from my prior weight problems that basically came from me being extremely obese at one time; had gastric bypass surgery in 11/2005 when I weighed 474; my current weight is 204 but because of my weight, I have a severe venous deficiently in my legs which is the reason why I have such a hard time healing with the wounds on my legs. I would appreciate any feedback and information you could give me regarding my situation.
