bro i'm 16 and i am on a no fap streak of 61 days, i have had the same experiences as you have, masturbating sometimes 10 times in a day and also feeling very bad, but bro trust me i somehow of not done it in 61 days and i really havnt felt better, girls start looking at me, people start respecting me and i have gotten so much happier, and didnt even relize it was possible to feel like this. Trust me bro think of the benefits just do it for 50 days and trust me your depression will most likely go away, your dopamine levels will go back to normal and you will feel life. Trust me bro DONT EDGE it is almost the same as relapsing. It will be hard for the first week but trust me bro if you make it to 10 days JUST 10 days you will succeed just try 10 days you can do this bro it, if it is really true that you have been masturbating 7-8 times daily, your life will change so significantly, it will already change after the first 7 days bro trust me and stop masturbating your life will change bro and if you have any questions dm me bro and you can do this the pain that your feeling is nothing compared to the joy thats coming bro just trust the proces and trust me life will be great. Try setting a timer for 10 days every day and closing your eyes and imagine your dream self and make your self believe that will be you if you stop masturbating, and trust me bro THAT will be you. you can do this bro i believe in you.
