I am asking to those who ever had any friends or family members who passed away of suicide? how does it changes you? whats the impact to the family and how to overcome it (if it's possible)

I am planning to end my life for the last couple days and the thought that holding me back is my family. Honestly, I never really care about them but I'm afraid if I die then i'm just gonna passed down the new trauma to the family and probably impact them badly. My mother didnt take it well when something happened in the family over the past years and before I was born, my parents had a daughter that was passed away at the very young age. My parents also know about my mental health situation and I'm afraid this will make them blame themsleves.
