Families sure can be a mess...mine included!
I just got a call from my ex daughter in law...and I really do miss her..but she and my son divorced this summer and he is already engaged to someone else..and there are 2 little girls (my grands) involved...its just so sad..
I guess it is every where...and sometimes we just all need big hugs.
I am sorry you are feeling so down and wish I knew what to say to make you feel better..
Just know you have people here that will let you get it all out...
hugs to you, sweetie
