Yes it actually gets much easier. The beginning is just hell because at first you have to go through EVERYTHING which is hard, and can bring up the same feelings. Just be honest with your psyc about how you feel near the end of the session and they can help you find methods to cope. I also had some substance abuse issues after a traumatic event (I also had childhood trauma) and at first it was hard, I had to conciously tell myself NOT to go into the liqour store, and grab a coffee instead. But with lots of thinking to yourself about how your going to get through the immidiate problem can help.

And I hope this post helped I'm not saying it will just poof vanish but it does get easier.
