IIN to want my therapist to think I never recovered?

I would say not normal. Firstly, allowing this person to continue to rent space in your head now that they aren't a part of your life anymore only hurts you. Also, Cuntsiclestick has a good point that if they didn't care about you while you were a client, they very likely won't care about how you are doing now.

Also, I believe there is a saying that goes something along the lines of "the best revenge is a life well lived". So, I think it would be better to continue to improve and live the best life you possibly can (though this should be something you do anyway, not just because of another person who was a negative influence in your life).

Honestly, who cares what this person thinks? I hate to say this, but it's likely they haven't thought about you since dropping you as a client and may not even remember who you are, so it's likely they won't find out anything about your life unless you have mutual friends.

Also, did they ever give a reason for dropping you as a client? I admittedly don't know much about that business, but perhaps there's a chance it wasn't anything personal? They definitely didn't handle it professionally by waiting until you showed up for what you thought was your next appointment to tell you, but unfortunately there are a lot of people in business who mismanage things like that.
