Porn addiction...

I'm scared I am borderline addicted to porn since this stupid lockdown has happened. My husbands sex drive is so low and I'm at home and bored all day so I've been watching it for a few minutes like once a day but sometimes up to 3 or 4... i need your suggestions on how to stop myself... i tell myself that i wont, and then in the moment I convince myself its okay to do or it will be one last time.. and it's a spiral. I dont want to talk to my husband about it because he doesnt like if I watch it... but i am so embarressed and i just want to stop and find the strength.. please try not to judge me to harshly.. I am in abit of a depressed state at the moment and ive always had an addictive personality weather its weed, alcohol or this.. any tips or tricks that works for you would be great... Thankyou
