Hi Steph,
I am sorry this happened.:(
Yes, I think the antihistamine should be well clear of your system by now...
...but of course triggers and anxiety can hang around unfortunately...and it sounds like this might be the case. The Benadryl was the catalyst, but now the anxiety is carrying on the effects.
We have some GREAT self help links in our Resources here. The link below will bring you right to them!
