Dave,

Don't worry, this is very normal. I guess that lot (most) of people get this after spending (to ) much time around here and getting more stuff and skills. I've had the exact same thing happening to me more then once...

My advise would be to calm down, chill for a couple of days, and then re-evaluate every kit you have and every situation what you would like to make your kit for.

Then just lay all your gear on the floor and think about every item and how it would help you to survive your scenarios. Don't be a pack-rat, but don't be a ultralighter either. Be reasonable for yourself.

Also, when in doubt: post it on ETS!

And of course...good luck!
