I have tried so many times to stop

It started when I was thirteen. I was over at a friends house and we desided to look it up from I was hooked. I am about 6 months later I was caught by my dad while I was looking at it. after that I talk to my youth pastor and started reading the bible and was off of it for almost 2 and a half years. van horn night I was watching tv and saw a commercial 4 porn. that got me thinking about again and then I slowly begin looking it up again. this has now been going on for about 4 months m and I tried to quit several times but have failed. I have been too scared to tell anyone until now. So I am finally telling every one on here that porn will no longer control my life.
