First of all your question isn't dumb ...

It's very difficult for me to form close relationships, and yes, sadly, I've had many friendships to fade along the way.

There are those that do understand and those that don't understand that sometimes it is all we can do to take care of ourselves.

It certainly isn't kind for any of them (understanding or not) to try and guilt trip us into taking on more than we feel we're capable of handling at any given point in time.

While I regret some of the friendships that fell apart along the way, I understand the how and why of it and don't wish any ill will towards anybody, most of all myself.

I'm doing the best I can.
