Here's my thoughts: firstly, just stopping therapy suddenly can be very hard and painful, and there can be a huge feeling of loss, and you can be left with all the emotions you were feeling in therapy when you ended all churning around you. (I'm speaking from experience here). If you want to stop, an option is to have a conversation with your T about it and do a planned ending. This might allow you to celebrate your successes and end on a positive note.

Secondly, you sound like you have a lot of emotion around the issue of whether you can or cannot get anything more from therapy at the moment. Can you discuss this with your T? Is there a possibibly that you can take a break to think about whether you want to carry on?

I also have felt a bit sad about 'needing therapy' at times. But perhaps everyone could benefit from good therapy if they tried it/ could find a good therapist?
