A wee bit down

IDK if it's just Monday, the nasty weather, or what, but I feel a little down.  I was in a particular group that over the year we have become close but a few dropped out.  I feel that when they did that, it was like losing my ex all over again....they are friends, and have know my secrets.  It's just hard for me to trust others and I feel like I have lost some wonderful people.  Again, I am alone.  Meh.
