i've experienced both of what you've talked about in this thread

the first part... anxiety to make changes, i get that a lot- with me it's like... my life is going past me really quick, i don't know how long i'll live for, so soon i need to make the most of things- start making changes... or i'm going to get to the end of my life having accomplished nothing. that scares me all the time.

the other part... yep- that sounds like a pannic attack to me too!

i've some pretty embarrasing experiences with those (which i won't go in to on this thread) but yeah... it's not nice!

good luck
