Addendum:
That "rocky/boaty" feeling you get is anxiety. I know because I have the exact same thing.
Your HPA Axis has somewhat balanced itself out after almost 3 years so you probably don't get that gut-wrenching anxiety anymore (the one that you feel in your stomach) but you still haven't 100% healed so you get that rocky/boaty sensation instead. Mine was pretty bad but has somewhat balanced itself out now. Even though I still get it when I'm worried about stuff.
