Ok, so it's a little late in coming, but here's my 2 cents....
I hope you're doing a bit better by now Fay. The up and down thing can be a real drag, I know. I'm having a similar sort of time lately. Up just long enough to start making plans and try to get stuff happening and then it all goes down the tubes when the low hits.
There're two things I've found which can make a difference. First, try not to rush anything. No matter what it is, good, bad, pleasant, unpleasant, pace yourself. Second, take time for yourself to just sit back and recharge. I dunno if it will help, but it does for me.
I know I haven't been around much for a while, but I'm still checking in on you mooks now and then so you better keep on taking care of yourself
