I could have written your post TSH - so I'm guessing, what with the other responses on this too, it's not 'us'...or not just us anyway.
I've been here for nearly two years...it's a big shock to realise that somewhere somehow someone moved the furniture.
Nands is right tho - SR does go in cycles, and maybe you just need to participate no matter what and it comes back?
Feels more than just a cycle to me tho. I'm just concentrating on the other areas of my life for now. Growth - and change - isn't as scary to me as it used to be, so I'm runnin with that
