Hi WALSH21
Welcome to NeuroTalk
.
In some ways my experience is similar to yours; I am in remission from Major Depressive Disorder and used to abuse alcohol. I can't say much about your physical problems but here are a couple of questions for you to consider.
Did you discontinue anti-depressants abruptly or did you do it slowly under medical supervision? This can be important.
Have you considered Cognitive Behavioural Therapy? In the hands of a skilled clinical psychologist this can make a difference.
Best wishes.
