working on anger

Talked with my therapist yesterday and big surprise she told me that the anger I feel is only hurting me.  We talked a lot about the betrayal too involving Sarah and how I am still hurt by this.  I can forgive her but I can never trust her like before..  She said this is understandable - and only in the future - when that relationship with the bloodsucker is over &  if she really tries to re connect with me should I even consider rebuilding a relationship - but she said it still won't be the same.  Until then time is the only answer.  I have had a lot of time and thought I was okay with it  but that was before the bloodsucker was able to come and work on my unit again.  It's like it's all up in my face again. This will get better - if not I am wanting to leave there anyways - just wanting for a door to open.  In the meantime - a lot of folks at work are snooping around asking about how I'm doing about the boss being gone, the bloodsucker coming back, am I leaving - just to be nosy.  I think they have noticed that I am more guarded and not as open as I usually am.   I have been working hard on boundaries with people - part of my homework - it's not easy as I am an open book.  Thank goodness for this blog, therapy, husband and true friends who let me release my inner feelings and don't stab me in the back.
