RE: Did I stall???
I would say you were definitely stalled.
Another aspect of stall recovery that many beginners are not used to: Once the wing stalls and the plane starts to spin, ANY control inputs other than throttle are going to deepen the stall. That is why stalls are frequently mistaken for radio hits. With a stalled wing, adding aileron will not have the normal effect, and that feels like a radio hit. Same with elevator and rudder. In fact, the control inputs make the gyrations of the plane seem worse. Thats how you ended up turned around.
When you're landing, try to keep the nose level, or maybe one or two degrees up. This will help keep you away from the stall condition.
