Derealization when trying to treat pdd

My therapist wants me to map out my feelings/emotions before, during, and after doing activities. However, with my anxiety gone on the new antidepressants I am trying (venlafaxine), I feel literally the same no matter what I do. I got a sheet that explains all the physical sensations one might experience based on what emotion you are feeling. The physical sensations I experience are quite literally the same regardless, with some fluctuations to my level of fatigue. It doesn't really help that I have been constantly dissociating(derealization) for the past few weeks too. I often find myself dissociating during sessions and have done so a lot in the past which makes me wonder if I have dpdr. It doesn't help that it is a side effect of the antidepressant, which I am currently in my third week of trying. Hopefully it will lessen up with time.

I just needed to vent a bit.
