Hello
It depends how you feel ' now '.. Do you still cut or not, do you feel your current life is ruined or not, etc...
If you are still cutting, it is obvious you need to see a professional. As the cause(s) of cutting are unconscious, you need to see a Psychoanalyst instead of a psychologist / simple therapist or even a psychiatrist. When the cause(s) is unconscious, I always recommend psychoanalysts. That is because only them deal with what is hidden in the unconscious and subconscious. Once the causes are relived, the symptoms like yours (cutting), disappear.

Don't think psychoanalysts are expensive, since most of them adapt their prices in accordance with the income of people. More you're totally free to search another if the first ones you found don't do that.
