I can't stop thinking about cutting my face

Everyday I have the same thought that I should just put the blade across my face and cut it open, there's a few reasons. The main one is that then people might see how much pain I'm in. Also really fucked up but I can't stop thinking about how cool it would look, I personally love all my scars and think they look cool, none of them were ever made with that intention but over time I really grew to love them and each one has a reminder within it. Should I seek actual help for this or just keep ignoring it??
