Having panic attack and anxiety when masturbating

hi im writting you because since the age of 12 i started masturbation and watch porn movie, sometime i masturbated 15 times day. since 1 year now i have a problem, when i masturbate i have panick attack and anxiety. i have heard that i have to stop to reboot my brain to be normal again, i made 1 month without masturbation, sex, and ejaculation and my brain was totally rebooted. But since 4 month i restarted masturbation and porn and i falled down. my anxiety was back and my erectile dysfuntion too. now everytime i masturbate, i have anxiety problem so i want to stop it but its hard. i do penis enlargement 3 to 4 times per weeks i do jelqing stretching and kegel. the question is even if i stop masturbation the time i reboot my brain can i keep jelqing??? when i jelq to maintain an erection i stimulate myself or think about a girl to be able to keep an erection during the exercice. i do it for 30 mn. please to answer me doctor because it ruin my life thank you very much
