I had the most stressful day today and that led to the worst panic attack I can remember in ages. Shaking, trembling and the creepiest thing--my hands went numb and then started to tingle. Has this ever happened to you?? I was at a big disadvantage too as my Klonapin Rx refill has been goofed up for 3 days now! I am completely out and I really needed one. I use them only when an attack is bad, so I'm not addicted to them, but right now I am under extreme stress from having to do long-distance care-giving for my Mom and I am wired and cannot sleep well as I try to resolve a major problem with her situation. I cannot let her down, but it is taking everything out of me. So, therefore, when this hand thing happened I freaked out and got worse. I have calmed now, but my hands are again tingling and I'm in "I think I'm dying" mode. Can anyone tell me that this isn't anything more than a usual reaction to stress? PLEASE!
