So I've been doing really well with my anxiety and haven't had any real issues since around February time! I think being in Lockdown not having to go anywhere helped.

But today, I don't know what happened (or if it's even anxiety!) I'm now back at work, have been for 3 weeks but in a new job.

Didn't get off to the best start, started unwell which carried on for a couple of weeks and now starting to feel much better.

However, today I have what I call an "episode" out of the blue. I laughed out loud and as I did, felt a pain in my left forehead. After that I got the strangest feeling/sensation. Like tingling, my teeth felt funny and I felt a bit sicky. I don't know how long the feeling lasted but it was awful. Then I had uncontrollable leg shaking. The kind you get when you're nervous about something and they feel all tense. Afterwards I just felt so tired.
By the afternoon I was absolutely fine.

Is this anxiety or something else going on in my head?
