I'd let go of the guilty part if I were you. I'd feel like celebrating only and wouldn't feel bad about it.

I had my own celebration when the board reprimanded my former T for his unethical actions and I didn't feel guilty one bit about reporting him. In my case though, he didn't lose his license. He was just put on probation for 5 years, which means he could still practice, as long as he fulfilled a number of requirements, which was to submit regular reports about his practice to some monitoring agency, to undergo personal therapy and to submit reports from his therapist to the board, to complete extensive course on professional laws and ethics, to pay the full fees of the board's investigation, to inform his employer(s),interns and new clients of his license probation status. Needless to say, he also had to pay for his required therapy and educational courses.

I urge you to look at this event differently. You are not the one who got her in trouble. She did it to herself through her irresponsible actions. You had the right to report her and it's great that you did it, because I believe taking civic or legal actions against those who harmed us is one of the most empowering and healing things we can do for ourselves. Please, do not take the burden of her problems on yourself. Her burden doesn't belong to you. It is hers and hers only. Let her do her own work. This would be a great opportunity for her to do some important personal work and, if she chooses to do so, to make her life better ultimately. But that is entirely her choice and has nothing to do with you and your own life's path. So, I'd say, let go of her issues completely and celebrate the emotional freedom you'll get as a result.

I, actually, remember vaguely you posting about it and how many invalidating and judgmental comments your post got. I thought it was unbelievable how many people were so eager to defend your therapist. Very disturbing..
