D..
Q., I wrote you two different posts and erased both of them. I don't want to sound rude to you, but one poster just said kind of the same thing, so I'll admit that I am having a really hard time understanding your post. What is agro? If it's an Aussie term, please restate so that we can understand.
I THINK that you are saying that you are the boy's father. (Q. is a man's name, though that doesn't mean anything in regards to this site.) If so, then you do need to take him to the ped and talk about the bruises. Don't talk about the bruises in front of your child.
If you are contemplating suicide, then I strongly urge you to get help. You are no good to your son if you are dead. If you try to commit suicide and don't, they won't let you near your son because they won't feel that he is safe with you.
Start with the ped. If you have a lawyer and can afford it, talk to the lawyer about what the ped recommends after having your child examined.
