It really depends on your religion.
From a Christian standpoint, it is. There are multiple Bible verses that actually directly address cutting.
Leviticus 19:28
You are not to make incisions in your flesh on account of the dead nor submit to cuts or tattoos. I am the LORD.
Deuteronomy 14:1
Ye are the children of the LORD your God: ye shall not cut yourselves, nor make any baldness between your eyes for the dead.
I believe it is a sin, because your body is a gift from God. You should not do anything to harm your body. If you are a Christian, it is also the temple of the Holy Spirit would you hurt God's temple, if so, then don't hurt your body as well.
1 Corinthians 6:19
What? know ye not that your body is the temple of the Holy Ghost which is in you, which ye have of God, and ye are not your own?

Talk to a psychologist about how you can't stop cutting yourself. He can help you. If you have a good friend, talk to them. Surely they can help you in getting your problem done and over with.
