I want to cut myself to make the people around me understand that I'm not okay.
Do you think cutting yourself should be used as a method to grab people's attention?
It would help them get the picture that I am in pain.
It might help them get the picture but the behavior itself to achieve that is highly destructive. It will turn into a habit and you will develop mental health issues that you will regret later on in life.
I will think about it but I might end up doing it anyways.
It's a start that you are willing to consider not hurting yourself to get attention, because wanting to do this will really only hurt you in the end. Simply ask for help without adding the pain and drama of self-cutting to the mix.
