after effect of over masturebation

Hi im 26 year old male and i am unmarried. I was addicted to masturbation since i was 12 year old. I usually masturebate once a day or twice a day. But 8 months ago i was addicted too much. I start masturebate daily sometimes 2 times or 3 timeaa day. Then one day i masturebate 3 time with a difference of 1 hour continuously. when i finished i felt shivering after 1 hour. I was really worried that what is happening to me. I didntknw that masturebate cause side effects. Then problem starts from that day usually before sleeping.when i go to bed i start feeling my heartbeat and shivering, and some thing wrong wih my mind. I cant explain but i felt some unwanted feelung in my mind something like stress. And i couldnt sleep. This prob continue and i go to dr. He took all tests related to heart. He told me ur heart i absolutely all right. Then he gave me pulls to reduce stress. In short when i use that 💊 i fell better. I use that pill for 3 months then i left it.
