It's been over two years that I started therapy, and I finished about six months ago. I think the stages have been something like this:

Stage 1: scared, uncomfortable to open up
Stage 2: learning to very slowly trust T and opening up more
Stage 3: feeling like T is going to reject me anytime now (transference!)
Stage 4: learning T doesn't reject me, no matter what I say or do
Stage 5: getting comfortable with T, feeling more equal
Stage 6: getting attached
Stage 7: feeling ready to end therapy
Stage 8: grief
Stage 9: doing well
