Least - I'm not sure of the complete story, so forgive me if I'm making you repeat yourself.....
but are you taking anything for anxiety? is this something you've always had or is it because of (or worse) from the withdrawals? if you're not, I think you should. you shouldn't have to feel like that - especially every day. and I quickly scanned your beginning posts on here where you said it wasn't life threatening, and it may not be - but it certainly can be dangerous. I used to take panic attacks, and hyperventilate until I fainted. and fainting on cement floors or banging your head off tables on the way down is not as funny as it sounds
I hope you can get things settled down soon. you should NOT feel trapped, or feel this bad. when I first started here you were one of the first people around cheering me on and offering advice. makes me sad that I can't help you out more now. please keep posting and let us know how you're doing.
(worried about you...)
