How do I stop cutting?

I've been a relapsed cutter for years. Some people who don't cut always say "just don't cut and talk to me" but they don't understand that every time I feel depressed or sad, I remember the past where I cut myself and it felt so good...but my mom found out and said that if I cut myself again, I would go to the hospital...this was about a month ago...I cut myself this morning...but lucky for me my parents are in Grand Cayman...but what should I do??? 
