Aww, I'm so sorry you are having a hard time. I get the shiver thing tho! I used to get panic attacks (about the same time maybe a little later) EVERY night about age 20. Anyhow, when I am anxious or really cold or even angry soemtimes I shake uncontrollably. I hope that at least helps you a bit. Can you get into a therapist? Maybe there is something else you can do (everything you said you're doing is great!) that you or we haven't thought of? It's worth a shot. Anyhow, I hope you start feeling better soon. We're hear anytime too, so no worries about "whinning" we all gotta do it sometime and it isn't really whinning, it's more like venting or seeking out friends which is perfectly fine and I'm gla dyou did!
