best advice to quit?

i'm 20f and since i was like 15 i was crying and listening to sad songs, to cheer me up figured id watch porn and have since then multiple times a day put on sad songs, cry and just watch it. I'm not even getting off on it anymore stopped doing so when i was like 17, it just became a part of my routine i've tried substituting porn for other shows but it has to be porn. its affecting my daily life i've missed social events and cancel plans to do this, ive lost friends over this and haven't held any relationships because they get uncomfortable im watching porn, i've tried so many things but nothing works for more then a week or so the longest was around 5 weeks like 2 years ago, the reason i relapsed was because i was crying about something and instinctively went to go watch porn and listen to sad songs, recently as i'm watching i almost feel grief for myself? i just get a heavy heart and stare at the screen and zone out until the video finishes.
i'm considering maybe therapy or something as an option to go ahead? it's been 3 days since i've last watched it so i'm hoping to find a resolution to help
