The fact that you've hurt your ankles badly several times, your parents' reactions, and the fact that it's an ongoing problem where you could suffer again at any time... I don't see the trauma as stupid at all! Just picking one of those factors would count as traumatic for me. There is nothing to feel stupid or guilty about. The fear you have is a healthy one (if you weren't worried about your ankles and pretended nothing was wrong, there would be serious consequences). I hope the next doctor you see is able to find a solution not involving surgery, or at least less expensive surgery. Take care.
