hello,
how long is a "long time"?
are you experiencing any other symptoms such as depression, anxiety, irritability, things associated with porn addiction.
have you ever tried to stop looking at it before? if so what was your longest streak?
if you could name three triggers that cause you to watch porn, what would they be?
by answering these questions we can give you some more tailored advice!
all of that positive thinking crap like "who do i want to be?" or "mission statements" (cringe) is all well and good, but it can clog the brain with a lot of uneeded rubbish, if youre constantly thinking about your "values" you may miss other more practical things.
its something to take one day at a time and to break down into small attainable goals. try to go three days without PMO at first, then extend that to five days, a week, etc. youll start seeing benefits!
