You haven't said that much re your symptoms, or what caused the attack...but I understand...if you're in the middle of a panic attack, typing/thinking clearly are obviously among the problems. I'd have to ask a) how often do you experience them b) do you notice that anything specific triggers them? c) Do you have racing pulse, shortness of breath? (more common in actual panic attacks, proper, than just anxiety, and therefore more likely to warrant a benzodiazepine) d) have you tried herbs/supplements, yet?
I can't meditate when I'm extremely anxious, either...it just makes it worse. I have to stay busy. Often doing something routine, but physically engaging can take your mind off of it, and help...ie cleaning the house, etc. Somehow, feeling as though I'm accomplishing something that makes me fee like I'm acting responsibly and productively helps my mood immensely.
I too suffer from anxiety...and I've found that pets help, immensely. There are even "rescue animals" for PTSD/anxiety related issues, now...you can take them anywhere in public with you. Do you have a pet? Have you considered asking you pdoc/tdoc for a "prescription" for a rescue animal. Just some suggestions. Be well
