Marriage counseling appointment...

Went to marriage counseling last night with my Wife. Things started out bad from the get go. I picked her up (which I will not do again for a long time) and she immediately started in on stuff she was not happy with. The trigger was her asking if after our appointment I wanted to go to have frozen yogurt. I really wasn't sure I wanted to and I told her so. The discussion quickly led to her wondering why we were going (to marriage counseling) at all. I almost turned around and took her home.
 
She did most of the talking during the appointment. I felt she was not being totally truthful with our counselor and tried to give my point of view as much as I could. Part of the session centered on my not wanting to stop taking my Adderal or stop vaping. She believes the Adderal has caused me to become a different person. I believe the things she is noticing is symptoms of my depression and anxiety. She has pretty much given me an ultimatum that if I don't stop taking the Adderal and stop vaping she won't let me come home and there isn't a way to make things. work. I feel like she has chosen two things she knows I can't change right now. It is like a wall I can't get through unless I bow to her demands. This all feels so hopeless. I am both angry with her for putting up such a fight over this and incredibly hurt and sad by the way she is trying get her way at any cost.
 
I am so tired of all of this. My depression continues to get worse. I don't see any way to get better with all of this going on. She is so sure that the Adderal is causing all of our problems that she won't even entertain the thought of anything else being a cause. I don't know how much longer I can deal with this.
