Well I'm glad your family is supportive. That's great. Your depression (PTSD?) is after a bully so if you talk to them and give them a flavour of what's happening they will rally round.
Your partner however. If not abusive is WAY out of line. I suspect he isn't a psycho but he IS bullying you and both his content and his delivery are completely out of order and some one needs to tell him that sharpish. Do you think showing him this would work? Or better yet printing it out, leaving it for him to find and going to your parents got a few days? Giving him time to reflect?
And his bullying you is causing your depression to worsen. I think also change counsellor. I've had depression and three counsellors who did nothing but make it worse because they just sat there. Talking about things I couldn't change from the past - when the problem was my present situation.
So the only thing that will help is whatever gives you the strength to stand up to him and get this situation in hand - or leave. He has no right to do this snd it's nasty, And hypocritical! People with adhd takes risks as children that are staggering. So his stance on this is just incredible.
Also adhd is genetic and starts around 2. If you have more than one child there's a high chance that one has it, Maybe this is more about his own self hatred and blame and you are just an easy target. Don't be,
Show him you are willing an able to leave and I think print this out and leave it. I know it's risky and bad advice for an abuser - only you know if he's controlling in other areas or just being nasty in this area and needs to control it and needs to hear from other people that he's being a prick.
If it's just adhd then he's aggressive and bullying but not necessarily cruel or calculated. If there's any element of control though plan your escape.
He needs to get his emotions under control and stop projecting his own feelings into you though. And he needs help to do that - and he needs to be better informed about what adhd is snd isn't and to be getting treatment. As do you.
But firstly he needs to know he's crossing a line and you will leave. That will help him no end.
