Anxiety due to Mastrubation. Me out!

Hello, I had an anxiety since last 2 years. I consulted a psychiatric and neurologist Doctor and I am going through continuous medication. When I asked to doctor why this happened to me he always replied how can I tell you it's not possible, take medicine continuously it will be alright. I don't see any scope of Improvement. I feel the same two years back what I felt today if doctor try to decrease the dose of medicine. I am Addicted to Mastrubation at the age of 20 and it's been 14 years now. I some how feel my anxiety started for this reason only but I am not sure. Sine last two years When I ejaculate, my heart beat start fasting after some time or days, continuous urination, mouth get dried, fear of something etc. Until my sperms get recovered in my body. So who can help me out regarding this? wheather I should consult a psychiatric, neurologist or sexologist?  Please help me. I desperately want to get out of this. I want my normal life back.
