The truth is, if your parents aren't abusive or non caring in any way, if your parents love you? Which I gather there do or you would not have this fear... The chances of them being wrecked with guilt is quite high. I'm just being completely honest with you. I do not want to pretend that there is a way to make loving parents not feel guilty over their child choosing to end their own life. But you can explain to them, in detail. Leave a detailed note about your pain, whether you have been thru anything traumatic that you need to escape (like myself) or are just plain miserable with treatment resistant mental illness or what the fact may be that has ked you to this choice. But if your parents love you, they do deserve some sort of explanation. Yes you deserve relief. But they deserve to know why, y`know?
