Way to panicked

This is obvious from my posts on here but I am starting to get concerned with the level of worry that I exhibit on a daily basis. I even worry about the amount I worry. It's getting to the point where its controlling my life and I have a constant fear or feeling of dread in my body. My most recent worry is the fact that I went on a porn website to confirm that I was straight cos I had some curiosities and I came across a video that I never watched but clicked the link to and I read the hashtags when scrolling down and it said it was "teenage" porn. That made me freak out and close the page. But now I am constantly worrying that the police will know I clicked on it and come and arrest me for child porn or something like that. I have searched websites to make me feel better about it and make me stop worrying and one said that it's okay as long as I am not a repeated offender and the fact that I never searched child porn into the browser I searched Male masterbation. Yet even with that knowledge I am still worrying and i cant get that constant fear out of my mind at all. I think until someone else confirms that what I read was correct I wont stop worrying so please can someone confirm that the information that I read was correct.

Also can someone help me about what I should do about my constant worrying about everything because I cant carry on like this anymore
