I've had anxiety for , but recently something has changed...

Hey, I have anxiety and ADHD. When I realized what I have, I made notes on what set me off more then other things, usual stuff:unlocked doors, open windows, screeching tires, stuff like that. I'm attending a college that requires that students go to chapel. This is my second day year at college and my 6th (or so) year of having noticeable anxiety so everything should be normal. But this year I've had a problem where I have a weird like shutdown thing when chapel starts. The first thing I notice is that I get hot and instead of singing along with the praise songs, I'm just mouthing along, until my jaw starts to clench. I just get insanely tense and uncomfortable. I wrote down some of the things I noticed that might have set me off and some of the other things I noticed:
The difference in time between the singers and the speakers
The difference between the speaker and the audience singing
The audience that is talking at the same time as the singing
Off beat clapping
Loud clapping
Hyper vigilance? Or just really good hearing?
Increased heart rate
Chest pains
Vision fixes to one place then gets blurry
Fidgety
Emotional feeling of having pots and pans banged together right next to me.

This happened several more times, basically at every chapel meeting. I am religious, so I don't think it's like, a psycho-somatic kinda reaction to not liking Jesus. I don't know what this is. Have any of you experienced this or know what it is? I'd really appreciate anything at this point.

I used to get panic attacks in church. Very annoying... also the mall, few other specific places.

It seems as if anxiety will go out of its way to torture you in the most unlikely places.

We're not supposed to excessively promote religion here, but since you're a Believer I feel free to say that, in addition to learning that i was having panic attacks (I had no idea at first), I also took the attitude that Satan was trying to keep me out of church, and I got very determined to not be run out of anywhere I wanted to be by no panic attack. Eventually, treating it as a battle of wits against either unseen forces or my own mind (whichever seems to the best way to look at it an any one time), it got easier and eventually the panic attacks associated with places that were not ordinarily stressful, faded.
