Hello. I can understand that this is quite troublesome and even embarrassing.
I would recommend you to seek a detailed examination from a good psychiatrist at the earliest. It is essential to clarify a few more points.
There are medicines (drugs) to help reduce and stop this occurrence. But can not be prescribed over the internet. Instead a qualified psychiatrist would be the right person to choose best drug for you after speaking with you in detail.
Next Steps
Seek a detailed consult from a neuropsychiatrist
