Hi,
I've had 5 hospital stays, 2 absolutely a horror show, one bad in ER and fine inpatient, and 2 that were bad because I was in a hard mental state.
Where I live psych hospitals are absolutely underfunded, understaffed, and overly filled.
Going back into therapy afterward was extremely hard, but that keeps me stable and allows me to maintain a job. I do not do well at forming thereuptic relationships either, but after about a year and a half I felt pretty comfortable with my current therapist.
Give yourself time and grace. Lots of us have had that experience of trauma from the treatment that was worse than what we went in for. Know you are not alone.
