It would be discouraging to have a therapist "discharging" you. Being discharged can feel like an end of any relationship. Like end of any relationship, you want to know why.

The form you mention sounds like the PHQ-9 questionnaire. It is a simple form to monitoring and measure the severity of depression. The questions you answer are used to assign a number that determines the severity of depression. Therapist can use along with their assessment to monitor how you are doing.

There is also a GAD-7 form that is similar that measure anxiety.

Though my depression is under control, I still see a therapist and it great resource to discuss issues and ask advice.

If you still have a choice, I would have one more appointment with the therapist just to get the answers to some of the questions you posted in your discussion.

I suggest you write down your questions in advance. Based on your posts, some suggestion for questions are:
- Exactly why am I being discharged? Maybe they feel you are doing OK and there is not any more they can do to help you.
- If discharged, what recommendations does therapist have for you going forward. Should you establish care with new therapist?
- If I want to continue to see therapist, what are your options. Maybe you can continue to go just not as often.

Are you willing to do another appointment to get answers to questions you may have?
