WLBG,
Well, I've had some mild depression at times, but I've never been diagnosed as bipolar. Sometimes I've wondered if I have a learning disability, but I've always done very well academically (when I FELT like doing well academically, at least!

) and in my writing, so I don't know. At any rate, I've made it to 46 without any MAJOR problems!
I'm not "officially" divorced, but it's on the horizon. And there's definite at least one "guardian angel", or something, looking out for me--always has been.
Lightning, I'm very shy and usually not a charismatic person, but when I'm feeling secure and confident (much better at that now than I used to be!) I can be pretty outgoing. When I am, I'd say that you're dead-on in saying it's a "defense mechanism". I can be EXTREMELY stubborn, and I do love my independence (although there are times I feel like being "looked after", too).
I guess everyone has had his or her share of suffering; I've had some, but I try to keep well aware of the fact that it's been NOTHING compared to what some others have gone through, and that I should always be grateful for that, and have empathy and compassion for others who don't have that "guardian angel" thing going on!
Thanks, guys!
