exhausted

I had my therapy again today and I am exhausted - it's hard to work on yourself!  My therapist says I need to work on forgiving myself...  how many times have I been told this?  I was a great session and I hope that I continue to get a lot out of it!  I went later over to a friend's house to chill - wasn't ready to go home yet.  Now I'm home and have decided not to exercise and I'm trying not to feel guilty about it!
