I have been masturbating from past 14 yr

Sir mam I have been masturbating from past 14 yrs and I cant stop myself I used to masturbate 4-5 times a day earlier and now it dropped to 12 a month. I am going to be 26 now. I cannot sleep without watching porn, feels anxiety, headache, urine every hour, back pain,sounds in bones, all my first finger has turned black and I feel some itchy kind of, I feel faint, can't lift weights, feels some urinary infection and going bald loosing hairs, I always think of p*rn all the time day n night, can't accept too much cold like I can't sleep in ac it will suffer me to a whole body pain, my brain is almost like dead I can't concentrate on what people says, i can't remember things I have much many problems I can't even remember now please contact me. I am a shy guy hence why I can't meet an expert. Please reply me thank you!
