Hop on finasteride and minoxidil now and start saving for a trip to Turkey.... Joking your not even receding, enjoy your life as a full head and stop worrying.
Welcome to the club. If you have started receding at 19, being honest its bad news.. but you never no might be just be a maturing hairline. Keep an eye on it over the next year and if it gets worse get on minoxidil and Caffeine shampoo does nothing for male pattern baldness.
Sounds like you are suffering from anxiety, tingling in the hands is a common symptom. But I would go to the doctors and have your blood pressure taken and ecg etc, for your piece of mind but I am sure you will be fine
