18 months out - waves lasting 2-3h??

hey there. affter having no big symptoms month 12-16, month 17 has been turbulent. usually a 'wave' (bad but not horrible) will build up slowly during 2-3 days, but I can feel the anxiety creeping in. all kind of symptoms pop up, twitching, insomnia. then it gets really bad for 2-3h, and everything calms down slowly. i'm like huh - thank you for leaving, but still feeling aftershocks, and fear of it coming back.....

after those waves, I usually get a good reprieve couple decent days....but I never know.  I feel like I can't distinguish anymore between normal life anxiety and benzo anxiety. which one is real?
