Therapy is an individual journey as She Cat has mentioned. There are so many variables that influence this as well. But for me the top two are: the impact of the trauma in my life, and the therapist I am working with.
I have been in therapy for 10 years with a total of 4 therapists and 7 guidance counselors at various schools and colleges. ( I moved a lot). I have finally found a Therapist who is amazing as well, which I know is very lucky. She helps me see my progress on days when I feel I will never get better, or feel stuck. Which is also reassuring.
Like Manic11 stated, you can always go back. There is nothing wrong with having an outsider with training to help you sort through thoughts, emotions and decisions throughout your life.
I think it's wonderful that in these two years of therapy you were able to discover your triggers, and learn coping mechanisms. Discuss your progress with your T and see how they feel about your work. Maybe you can try a trial run where you see them less. For example I see my T once a week for a two hour session. During times of struggle, I see her twice a week. Maybe you could reduce your sessions to once every two weeks, or once a month and see how you manage with that.
I wish you luck with your journey and good health.
