It is not a home. It is a jail. She is the warden and the only inmate. No visitors are allowed. When a friend or a family announce a visit (rarely, if ever), I am terrified of dealing with her stress.
It is very stressful to live like this. Don't underestimate the toll it takes on you. Continuing with getting therapy as a means of gathering more support for you. But also consider getting other forms of support.
A possible idea is to establish a home away from home? Somewhere where you can actually unwind and have privacy and safety.
