Claritan,
I posted that friends stay and friends go, in another thread.........
You , and we all, have quite a bit on our plates that we are sorting through.
And adapting to, and readapting to; rearranging and readjusting as time passes and things change.
These things draw us into ourselves more and more, and it becomes difficult to see whats going on around us quite often.........until we get a chance to look up and see that alot has changed, and our friends have moved off, our family has distanced themselves, or whatever has changed.
In one of those links above, there is a "letter to a family" , that tries to explain how we may look to them and what is actually what is going on inside our shell - and our friends are sorta part of an extended family .
It might be a good thing to Link in a email to some of your friends to see if it helps them understand what you are / have been dealing with, by way of an explanation that you haven't been able to explain otherwise.
Best wishes, and remember, we are all here together for each other.....
