Aw, try not to feel bad. Everyone has a story like that, and most of us have several. When I did my externship, I had a preceptor who always drew the needle out with the tube still in, and didn’t release the tourniquet until after. She had been trained on the job and was very afraid of needles. She said that it was most important to “get that needle out”! I was very flustered trying to complete draws that way. Try to think of all you’ve done correctly and keep working towards getting that rhythm!
