"You survived" doesn't mean "You're fine now". It means just that, you survived. Whatever choices you made, you survived. You lived. You are still alive, and that is a big achievement. It might not feel like it. It might feel that you 'just' lived through it, but you didn't, you survived whatever ordeal was thrown at you.
I don't know you, I'm not sure if I've read any other posts from you here on the forum, So I don't know your trauma, but if you have PTSD then you have lived through a traumatic and likely life threatening event. Some people who have gone through similar to you may not have lived - you are alive, that makes you a survivor. The fact that you are in therapy to try to resolve your issues and make your life better - that makes you a fighter. Just the fact that you are seeking help, both here and with a therapist - that makes you a survivor, (and one who is seeking to thrive and move forwards.)
Alive is actively breathing, (with heart beating), surviving is facing a threat to life and being alive at the end of it. Thriving is doing all that you can, when faced with adversity to make your life better than just breathing. You're already surviving, and your trying to thrive.
No, you are not fine. But you are doing everything in your power to be fine. What more could anyone ask of you? Don't let one phrase trip you up. You are doing what you need to do. Therapy is hard enough, try not to beat yourself up over the interpretation of a few words.
