I resigned from a position due to stress caused by Hostile work environment do I have recourse

I was employed by the Comm. of Mass/DDS for four years. I was a Residential Supervisor 2, I managed two group homes for individuals with MR. After working my first year successfully, I notice, as did coworkers that my immediate supervisor was rude, brash, hostile, towards me. Only me. I asked to have a mtg to discuss my observation. That only made her madder. From that point on, the next three years were terrible, my EPRS was not completed so I did not reflect her attitude. In the past two years running the houses became more and more difficult, both houses being medically involved, and with staffing issues, I became ill, stress induced and my supervisor tried to have me removed from my position stating she was concerned for the safety of the individuals. I was eventually cleared by my PCP to return to work, I used up ten weeks of accrewed comp time and sick time. I returned to work and was brought in for Show/Cause hearing that I did nt do my work correctly and had made mistakes in various places. I had repeatedly ask for assistance and more staff, I was informed repeatedly that there was a hiring freeze on and no more staff would be hired. I returned to work in August 2011, I resumed work, and that supervisor removed from covering my houses, the new supervisor picked up where that one left off and immediately found an audit error from 2009 and wrote me up on charges for it. I was never made aware of such error, nor given the opportunity to review it. With the same concerns as the prior administration and with the same stress, I resigned my position effective 11/21/2011. This pervayor has now split the two houses and given each house a manager and its own staff. Each is its own entity now!
This is what I had requested long ago and was told due to budgeting constraints it was not possible. Do I have any recourse, along the Harrassment/Bullying/ guidelines, they should be responsible for my 10 week comp time useage, they caused the stress.
