Grief

I'm feeling a lot of grief right now.  My husband, who has diagnoses of ADHD, anxiety, and depression, did something that exposed me to legal liability.  If the injured party chooses to pursue me, I could end up paying thousands of dollars in damages and might be subject to discipline by my state's lawyer regulatory agency.  Because I have no way of preventing my husband from engaging in further behavior of this type (or other illegal or negligent acts), the only way I have to protect myself and my livelihood is to get a divorce and forbid my husband from being in our house.  My husband and I have had a lot of problems over the years, but I've never before felt that total physical and legal separation was required.  Now I do.  Does anyone have ideas for how I can pull myself out of the pit of sadness I'm in now?
