Writing my suicide notes (14f)

Im already half into my moms note but im just thinking about something i could write that she can look back at and smile, reread and have memories in her head, or if thats gonna hurt her even more? Im making one for my mom, sister, and 2 brothers. And one for my dad that doesnt deserve it at all but i also want him to hear last words. My life is so miserable i have felt this way since 5 years and im ready to give up. I never truly felt loved by any person. I cant wake up with a heavy heart everyday anymore, its dragging me so deep. I hate hurting people, i feel like the most horrible person ever for doing this to my family, i feel so selfish and undeserving of anything. This si the best choice i can make to stop this suffering, the last time il ever hurt someone. I felt incomplete my whole life, something is missing about me and i cant seem to ever find it. I also hope my dad gets happy that im gone. He wanted to shoot me anyways. I am so alone
