It's a huge adjustment, and it takes time, that's for sure. Slow down as best you can, and live moment by moment.
I had more problems with depression than anxiety, but the few times that I experienced it (anxiety) it was absolutely overwhelming. I know you mentioned maybe taking something for it but be careful - I got prescribed clonazepam (benzo) and got hooked. Maybe ask your therapist about some natural stuff you can use breathing techniques, meditation, anything like that which can maybe help you to slow down.
Keep us posted.
