One way that I can think of is through the relationship with your therapist. I am not sure how long you've been seeing her for, but as you grow to trust her more, you will probably find your emotions "thawing out" ... and you will suddenly find yourself crying. It will probably take a long time for you to be able to feel and express any anger ... but when you do, and your therapist doesn't abandon you, or react in a negative way, it will be very healing.
I hope this helps,
