I think that's the cool thing about this place... while some of us are going to be down at any given time, others will be doing ok-good. And we can all pretty much understand what it's like to be on the other end, so some can give and some can receive and that can switch around and it works out.
I've felt like that recently, taking too much and giving nothing, but now I guess it's ok, because I know I can give as I'm able, and when I'm needy I can receive, and that's how it works. I hope you won't feel too alone in this.
