Is suicide wrong?

I'm 37 years old now my body is covered in scars from how much I hate myself. I have been like this since I was 14 years old. I would do it but the truth is I just don't have the courage. I have suffered since Im 14 that means things will never improve they will only get worse.

I have seen doctor after doctor I'm exhausted. I ask myself how bad is sucicide Because your not hurting anyone else. If I'm suffering I should be free from pain.
