Anxiety back after 2 weeks break

[Skeeble]

I am new to this panic disorder malark and anxiety. Only been having issues the last 2 months. Was put on propanylol and after upping it to 20mg 3 times a day i managed. Ive had 2 weeks of no panic attacks, my throat losend i started sleeping well. And i went for my first counselling session yesterday and wham its all back. Started coming back 2 mins before i walked into the session. I genuinely tricked myself the panic attacks had gone over night. Anyone else get breaks from there attacks and anxiety then they come back suddenly??
