Lost & confused
I'm glad you decided to post here at the Forum. Your story sound absolutely terrible and a complete nightmare, leaving you in pain, confusion and turmoil. If it was me there would be anger and self-doubt too.
The way you have set it out makes it quite plain that the marriage is broken for good, there could realistically be no trust in the future even if you got back together.
Frankly in a situation where the partner's family is against the match then the partner has to go one of two ways. Side with the family, thus devaluing and failing to support the spouse, or consider the spouse first and disregard the family.
Unlike your husband I had a total break with my family over marriage - best thing that could have happened.
Here you not only have the first of those two situations, but also the further complication of mental illness on top.
As this is not a overnight thing, but has been going on for 12 months I'm sorry to say I think you are well out of it and need to firstly look after your own well being and secondly start a new life (yes, I know, terribly hard to do).
While it is very sensible to seek help, a psychologist who is a mess himself sounds a total liability. May I suggest you go to (or return to) your GP and seek a different health professional? Anxiety and Depression need proper treatment. As someone who has suffered both I know I could not soldier on by myself - I needed outside help.
Do you have a family of your own, or a friend or someone else you can talk to, who will support you and understand? I found I could not have coped with my illness without both medical and personal support.
One ray of sunshine is that you have a good job. When times were bad I found having work to go to was a real blessing - plus of course having your own financial resources makes a ton of difference.
While you are here, you might like to look up information on anxiety and depression in The Facts menu above, and also have a browse of this Forum to see how others have coped in similar situations.
I'm sorry to have been blunt. Unfortunately I don't know any way to sugar coat this situation. All I can say is please post as often as you'd like, you will be met with care and understanding
