Tammy,
I am sorry you are going through a tough time...........I learned very quickly if you are in a supervisor position, you cannot be best friends with the people who work for you, it just does not work.
They want favoritism, and you will not be able to oblige them. They get angry at you as now you are their boss and not a peer anymore................if this is to hard to deal with are your willing to step out of the supervisor position to regain friendships or will you be able to draw the line between being your friends boss and still maintaining a friendship outside of work?
IMHO I would really like to see you talk to your "shrink" as that is why you have one, talk through your problems and recieve advice, remember you may not like what your therapist recommends but at least talk about it. You are the one in the drivers seat here.
I am sorry your hubby is not more supportive and also for the loss of your baby. That is truly a traumatic loss and you are allowed to grieve in your own way.
Many gentle hugs to you and please stick with us.
Kitt
