lizatola, I find that I'm decidedly low on friends at this stage of my life too and can relate to that part of your post. I give you a big pat on the back for doing what you ARE doing to remedy that situation.
I've recently started doing some activities to meet people and hopefully make some friends too, and it is uncomfortable at times...but it has to be done for growth, right?
Your post seems pretty insightful to me, and again, good job on moving ahead, even though inertia and the damn "comfort zone" want to suck you back in w/their tractor beam!
