Well the question is, did the hospital stay bring about any new anxiety at all? PTSD is old anxiety / events that a person should have got help for at the time. But they didn't. Could be months, could be years, but it always comes back to bite them hard. You are talking about July. You think you got PTSD from the hospital trip? Just seems such a short amount of time. Any anxiety would be normal anxiety still. Unless the stay cause you some trauma. That is only coming on now. You close your eyes and you are back in that hospital. You still see images in your mind from your time in hospital. Or are you talking PTSD from many years ago. You'll have to explain where the PTSD is coming from. Both are possible together. But you would understand why. Like if you were in a car crash as a kid. Might come back and haunt you later in life. Tell us a little more and we may be able to give you a better answer.
