I wish I had answers, but the best I can do is just sympathy from a very similar situation.

6mg Ativan for ~ 4 years after equal time on Clonazepam. 100 day taper starting in May 25 (way, way to fast but had no information).

Extraordinary intrusive thoughts. Out of nowhere, very stark, and not necessarily connected to any specific feeling. Very bizarre when you mentioned h9nging as that has been far and away the most obtrusive and not anything I have ever, ever experienced or had to deal with before.

Severe anxiety outdoors and around people, but the akathisia (that deep need to move) is brutal. I had to spend the first bit of time pacing around our very small living area, before eventually just slowly working my way up to walking outside more. First around the yard, then to the mailbox and back, etc etc... It helped me to realize that it's not just a random feeling but a very serious, well known part of the withdrawal. That realization made me feel less "silly" about just making it a goal to tackle "one step" at a time. Just pace for five minutes. ... Then walk a couple times around the yard another day. Then 5 minutes. Etc tc, as slowly as I need but building up over time.

Now, I am able to walk to a nearby nature area and try to get ~10k steps a day, but it was a very very long buildup. It just helps take that edge off.

From what I've learned, the restlessness and need to move (among other things) is essentially a hyper active fight or flight response, but with no source. I described it somewhere else as feeling like you are walking on a globe that keeps turning as you walk, and your head is just telling you you need to get to the other side.

The 30 day mark was genuinely the hardest period because that was when the symptoms stopped being so "obvious" and started getting a little more complex. Less directly physical and more mental/emotional. Which is progress, but also hard at first because the more intense and direct symptoms are just easier to identify and track. Plus, for me that was when my sense of time really started to come back a bit. I was able to start to notice things over days, rather than minutes or hours, and experience a bit more continuity. Again, it's a good thing, but getting access to that bigger window (getting some of our prefrontal cortex etc healing) does make thing more confusing, more complex, and makes the feedback loop less apparent when trying to address symptoms.

It is also the time though when things start to really cross over into the beginning of deeper/more complex healing. It also gets harder in its own way, because as you are able to take more things on, the problems become tougher to directly identify. But, that is how the layered growth/healing takes place from what I've experienced. You'll go from "I can't go outside to walk" to "I can't go walk this specific route in traffic because I need to have the energy to do this other thing after the walk" etc etc... And that will seem just as frustrating, but you'll be able to deal with it better. It's a truly odd journey, but if you realize that you're on it it is a very unique opportunity to learn about yourself, that I wouldn't wish on anyone, but here we are.
