When is the right time to end therapy sessions?

When is the right time to end therapy sessions?
Through my teen years I watched Sex and The City and the girls talked about seeing therapists as if it was trendy, as if it was the thing to do.
I started seeing my therapist in October 2017, and seeing her has been beyond helpful in teaching me ways to break my obsessional traits and take back some control from my eating disorder.
When I went to her I was clinically classed as anorexic, lacking in mental stability. I had no concentration, I couldn't care about anything properly.
Since seeing her my weight has gone up to 8 stone. My BMI is now in the healthy range, at the low end but still in the healthy range.
I know she has helped me a lot but I do long to see if I can manage alone.
6-7 months isn't a long time in terms of having therapy, not at all, so I wonder am I ready to try alone?

The true miracle is not walking on water or walking in air, but simply walking on this earth. ― Thích Nhất Hạnh

I have a new respect for life that I didn't have when I was seriously unwell last year. I was ready to let go of life and waiting for my way out.
Now, for the first time in several years, I really want to be alive.
Therapy has given so much back to me.
I am not fully recovered, or even close, but I have gone from 20-25 laxatives daily to 12. And I now have to knowledge to lower that number further.
I have more control now than I've had before with this disorder.
As we strive to destigmatise mental health, I know the thought of having therapy becomes destigmatised too.
Far too many people are afraid to ask for help or ashamed, I was for many years, but therapy has given me a chance at life again.
Whether I do the rest of this journey alone is not important, whether I continue to see my therapist every week or only once a month doesn't matter. What matters is seeing a therapist in the first place probably saved my life.
