Ok.

I think him not taking meds and not seeing counsellors is a bad thing- how is he supposed to get help?

Further, how are you supposed to help if you can't encourage him to do these things?

Perhaps what you could do, is find some books on anxiety and panic attacks and try and teach him some things you have learnt, or perhaps give him some books or resources. I think ideally he should be seeing someone-anyone, and whether he takes meds or not is a personal choice- some people are opposed to it, although i would not have got to where i am without them.

I am sorry you are in this position. Keep posting to let us know how you are doing.
