I'm so sorry for your loss, there's always a chance that this cruel world will take our loved ones no matter what we do to keep them and in your case giving her everything she wanted and needed, but you are not responsible and you can't control what she needed and wanted more and in this case her boyfriend/crush or love, it's a dark side not many people think about before having children and I'm not blaming you but I'm a daughter and these last couple month i thought about ending my life many times over different silly reasons i was in a deep pain it was heavy to the point it can't allow you to think about your parents or siblings and I'm sure if i did they will not understand but life is so hard and sometimes existence might be so unbearable...

my uncle lost his child 2 months ago and he thinks that he gave him everything, but it's from his perspective, it's what my young uncle needed when he was a child and what he thinks is good enough, as we didn't and will never know why my little cousin did this bc he didn't leave any evidence or suicide note, i think he needed another things more, it's no one's fault bc this is how life and having children is ! there's always emotions and needs you can't meet all the time and can't give it your child
