Dear X, X, X, X,...
I never thought I would write this letter, but life has been tough on me lately, and I do not see any way out. Before I leave, I want to tell you how much I love and appreciate every single one of you. My short life has been a rollercoaster ride, but it has been made bearable with your love and support.
X, my dear mother, I want to thank you for being the best mom in the world. You raised me with so much love, care, and affection. It breaks my heart to see you struggle with Alzheimer's, but I promise you that I will always love you, and I will be watching over you from wherever I am. You taught me how to be kind, loving, and patient, and I will always remember those lessons.
X, my dear father, I want to thank you for being my hero. You were always there for me, even when you were not around physically. You taught me how to be a man, to be strong, and to never give up. I am proud to have been your son, and I will always cherish the memories we shared.
X, my stepfather, I want to thank you for being an amazing dad. You may not have raised me, but you stepped up and took on the role of a father when I needed it the most. You taught me how to be responsible, how to be a good man, and how to love unconditionally. I am forever grateful for everything you have done for me, and I will always love you.
X, X, and X, my dear siblings, I want to thank you for being the best siblings one could ever ask for. You were always there for me, through thick and thin. You supported me when I needed it the most, and you made me laugh when I wanted to cry. You made my life worth living, and I will always love you guys.
I know my decision to leave must be causing a lot of pain and anguish, but I want you all to know that it is not your fault. You guys did everything you could to make me happy, but I was just not strong enough to face the challenges. I hope you can find it in your hearts to forgive me and remember the good times we shared.
Please do not blame yourselves for what happened to me. Life is unpredictable, and we do not know what tomorrow will bring. I want you all to know that I am at peace now, and I am no longer suffering. Please take care of each other, and never forget how much you mean to me.
I love you all, and until we meet again, keep smiling.
Sincerely,
[MY NAME]
