You need to figure out what situations you are more likely to engage in those kinds of activities. Then, you avoid those situations like the plague.
That is exactly what you need to do! If you know you will be tempted by coming on the computer, stay away from it.
When you say you need help, that is so true, but you need more help then you can receive from the Internet, you need Jesus' help. I can tell you from my own struggles with sins, you can't stop without his help. Pray, read the Bible, draw close to God, the closer you are to him the more likely you can withstand the temptation. I highly suggest you read the book of James, this book has helped me so much with overcoming my sin.
James 4:7 Submit yourselves therefore to God. Resist the devil, and he will flee from you.
Anyway, I'm no expert when it comes to this subject, but I figured I'd give it a try to help a brother in Christ.
