I've got GAD, and ordinarily I'm able to get by and have coped using mindfulness techniques. But the last few months I have been struggling to cope and have been verging on panic attacks because of really minor things - eg close to tears just because I was talking about myself 
I haven't yet been to the docs because I know he'll suggest ADs, and I really don't want that again - I'm not depressed just really anxious all the time. I have tried Kalms, but they don't have any effect at all. I had diazepam once and it had a limited effect - perhaps a higher dose would be helpful? I've had cbt and didn't find it much help at all.
