amandalouise makes some great points. DID therapy is a longterm proposition. Integration is really a natural process. The human organism naturally heals, the opposite of entropy, amazing stuff. Taking some deep breaths and accepting just where you are right now is a great first step. Finding and working with a therapist you can deeply trust is essential.
I look at integration (which I have not achieved) as gathering up, listening to and loving lost pieces of yourself. As you do that, these parts will be drawn to each other and care for each other. But it takes time.
Hope this helps.
