Therapy making my anxiety worse

Hi, My name is Grace. Ive been going to therapy since March of 2013. Overall it's been beneficial in helping me to address some underlying feelings about various trauma that I have dealt with throughout my life. But a few weeks ago, I decided to disclose being molested by my cousin who was only a 5 years older than me when i was 5 or 6. Since then I have been in a seemingly downward spiral and My therapist has noticed that I am having more PTSD episodes than I was when I first started therapy.
I have learned that I am codependent on my mother and she is dependent on me. That directly stems from having an abusive father and severely disabled younger sister.
I also feel as if it's strange because I havnt cried in therapy yet. I just choke it down and continue to talk through it. It makes me feel worse but I am afraid that if I let loose a little and cry I'll completely lose control. An since therapy is the only place that I feel heard, I feel like I should hurry up and talk fast because if I dont I fear my therapist will get angry (my mother has done that to me all my life so I suppose I should mention it in therapy). But dont get me wrong, my therapist is great! I even experienced a bit of transference with her which I've read in the right amounts is a good thing.
I just feel like I'm hindering myself by not being able to let go.

Therapy is a good place to cry. Really.

I had a similar experience with starting therapy making my issues worse for quite awhile. I had a group T once say that is to be expected because we're finally addressing our issues rather than using our negative or destructive coping mechanisms to avoid the issues, so of course it'll be tough. And it's so important to continue to learn to both deal with the issues and self-soothe when the emotions run too high. I hope you're able to let go in therapy, as it can be really freeing.

Yup my SI escalated from therapy.
