im lost

i am currently 16 and have been addicted since 10 years old, i feel as if i have no problem but i certainly do; i keep telling myself that my depression and unwillingness to do anything is just depression rooted in something else but i am honestly wondering whether it is porn or not, i have tried to quit before and the longest i have gone is three days in the past 4 years(before that i was much better only doing around 2-3x per week). i find porn and masturbation as a time filler, and at first i blamed watching it everyday on my hormones and saying it was just a normal thing but in society it is clear as day that my beliefs would be outcasted, im fine with doing it currently but i am unsure as to when i should fully cut it out, hearing stories of married men watching porn is unsettling and i don’t want to be in that position
