After five years I don't know that you'd begin having side effects of all of a sudden like this. I work in the field and those usually occur at the start and once your body tolerates it you're "good."
Those are def signs of anxiety.
I have bipolar I and anxiety/panic disorder. It sucks when it turns physical.
However, I have seen instances where after prolonged use of the medication they become less effective managing symptoms. Now this isn't something I've seen often but I have come across it. The fact that the Ativan and kpin do nothing must be incredible hard.
It's difficult to diagnose. My advice would be to see your psychiatrist immediately to see if this is possible. I can only imagine the horrible effects those symptoms have had on you and hope you can get them under control asap. I'm so sorry nothing is working to make it go away. The fact that Ativan isn't working is a red flag maybe you need something stronger but I'm not a doctor I want it to go away for you.
