Yes I've experienced this situation to be totally normal I am coming up on one year and I see my therapist twice a week. I have experienced ups and downs and some really really Lowe's so yes things do tend to get worse before they get better. The problem is my therapist has explained it is that when I started therapy I was numb I felt no emotions at all now I'm starting to feel emotions and that hurts that's painful. But he said the only way to get better is to work through being able to tolerate your emotions he said that even when I was numb the emotions were still there and they were still affecting me which is why I would stuff them down with food but now I'm feeling them more and so it feels worse.

Also as therapy has progressed I have learned that I have DID and as I've started to communicate with my parts I'm regaining a lot of memories from childhood. These are not good memories although I never really had any good memories before either.

The good thing is it sounds like you have a really good therapist who specializes in trauma. I am lucky in that respect as well. It is a long slow process and it is not linear it's not just going to go up it's a rollercoaster. I've been journaling for most of the past year and sometimes when I feel that things are the worst it's good to look back at some of my old journals to see how far I have come. While experiencing emotions sucks I have seen improvements in other ways but I know it will take a very long time to work through all of my issues. Try your best to stick with it things will get better eventually.
