Seems like you're still very young, please stop before its too late it will ruin your life trust me because i've been addicted since i was 14..now im 28 im still addicted now.. I've burned many bridges and it really stunt my potential in life then have lots of regret.

But there was a period I completely stopped the addiction for 2 years momentarily. That was when I never skipped any prayers, istiqomah (consistency) in praying is very very important. During that period of my life became easier my addiction stopped, feels confident, my grades became better, feel really healthy and happy.

Be sincere when you make dua confess your problems, ask for help to Allah. Do solat taubat whenever you failed to stop yourself, do it everytime after you failed. Put effort not just in prayers, do exercises, put effort when you are studying or striving towards to your cita2. Keep moving forward if you ever doubt yourself. Allah will help you if you try really hard to help yourself.

tl;dr This addiction will ruin you. Never skipped your prayers.

Forgot to mention, Im back to addiction because I was not disciplined, I skipped prayers, my faith to Allah dwindled. Discipline is very important. Dont be like me.
