My anxiety gets high when I'm hypo/manic, so if you are hypo/manic, I can relate. I think agitation can be experienced as anxiety, and agitation is listed as one of the criteria for hypomania.

Anyway, I tend to behave the same way when my mood is "up" or when I'm experiencing dysphoric mania. Chewing, lip smacking, loud TV, etc. p!sses me off to no end. Drives me up a f**kin wall.

I was feeling this way 2 weeks ago.

The best thing I could do was isolate myself when certain things p!ssed me off. For example, if your girlfriend's gum chewing irritates you, just do your best to walk away. I know it's not easy, but you'll thank yourself for it later. If you tell her that her chewing annoys you, she might get really offended and upset.

But of course, do explain to her that you're irritable and tell her not to take anything personally.

Best of luck. Maybe your doctor can help? I know you're going for a physical, but your doctor could possibly give some advice.
