Hi believer, I'm sorry you're going through such a hard time

But firstly I've got to
really commend you on finding your way back from/finding yourself after your previous relationship.
Real kudos to you for that!!!
And after being in one abusive relationship it can sometimes be hard to see the signs or confront abuse in another, just like the thought "just shut up and take it and be submissive, it will be easier" so I've got to really admire your strength in challenging that.
Good on you, real good place to start.
Now maybe his mixed episodes account for some of what's been going on, with irritability, restlessness.............and the rest going on in those episodes, but it sounds like you're paying way too high a price here, right??
So could you get him to agree to see his doctor/pdoc?? Get him to agree for you to go along with him to explain a bit more what's going on, maybe he's having difficulty raising everything/recalling or putting significance on things??? Or if that's a problem maybe his doctor/pdoc would accept a letter/email from you detailing everything, they might not tell you much due to confidentiality but............
And are you sure he's taking his medication as prescribed?? Maybe worth querying with him in a non-accusational/non-confrontational way??
Maybe there's a friend, one of his family members you could tell your concerns to who might be able to help or encourage him to get some help?? I'm assuming you've already tried talking to him about the issues.
But ultimately there has got to be a bottom line here, right?? You
have got to think about yourself in all of this. And you know you don't deserve to be in an abusive relationship, right?
No-one does!!! So if no answers/resolve is coming, you really have to put yourself first. And although walking away may seem so hard, just remember that strength you
so clearly,
definitely have got. And how important it is to "Be yourself"

And with the depression/anxiety........of course make sure you get all the help you need, but it's also good you've found us
You're going to find so many understanding and supportive people on here, so if you want to talk...............
