help me please

Hello, im 18 year old female, and my addiction to porn started after i heard and watched from a friends house, i still remember it, the porn was about a girl in a restaurant with so many men, it was blow job, double penetration and kind of fetish. Since then i would go to some online porn like redtube, youporn, pornhub,youjizz and many more, when im horny. Im not lesbian but i really love to watch the lesbian thing. Im suffering for about 7 years, and id really wanted to stop this addiction. My parents and frirnds didn't know about it, but it was very very shameful if they found out that im indulging myself with porn. I really want to stop this, i dont want my laptop to be my partner in life.
