Day1 :Some question and advice

Hi, first of all im 16, i have been masturbate since i was 13, i often do it 2 time a week. the reason i want to try reboot because sometime i feel depress and im having social anxiety and lack of motivation in school and hard to concentrate
Also, does nofap make penis longer, because if it does then it surely a big motivation for me.
Any advice on reboot would be appreciated, thanks
Sorry for my bad english
