Welcome to HCM
We understand your concerns
I went through your problem description. I suggest you not to worry too much. Such problems are common worrying about it increases the stress
associated with it. You are able to tackle it successfully and that itself is motivating. Good job.
Your description underlines the fact that you are Hypersensitive to loud noise. This could be anxiety
related (related to development) or a health condition named Hyperacusis
Proper diagnosis is important. Developmental disorders can be treated with behavior therapy and desensitization therapy. Consult a physician for proper diagnosis.
Hope this clears your doubts. Available for further clarifications.
