I feel off all the time

3 months into emdr for severe childhood abuse (sexual, physical, emotional and incestual abuse). I have made a number of very positive realisations and my therapist said I process things very quickly. After sessions I feel so fatigued, I’m napping everyday. I want to be alone all the time. I feel weird around others and I’m struggling to mask it. I’m alone in my bed with my rabbit constantly whereas I used to be so outgoing. I feel emotionally depleted and sad all of the time. I’m still functioning, I work full time, I go to the gym regularly (fatigue dependant) and I have a good life. But I feel like I’m going through life in an emdr daze.
Just needed to get this off my chest
