I'm sorry you feel like this and hurting. It sounds like you are having suicidal thoughts and everyone is aware of it. You don't want them to prevent you from doing it but you want them to care. I doubt this both possible.
I have no doubt your family and friends love you and would love for you to stay here with them. When you share your suicidal thoughts we inadvertently place our lived ones and friends in a compromising situation. If they don't call for help we feel they don't love us or care. If they do call for help we get upset. You may feel alone during this time but trust me, they are dealing with how to help you and probably scared of you harming yourself. Most people simply don't know what to do or who to call when we share this info with them.
Some options are venting safely on this site. Try having a conversation with them excluding any suicide talk. Or try spending your last days with them and try to enjoy their company.
I have learned it's extremely difficult for people to enter our world and understand us. Try entering theor world and spend those last days and moments with them minus your SI. It makes people uncomfortable. You can write goodbye letters to them explaining your reasons. I'm sorry if this wasn't helpful or the advice you were looking for. Whatever decision you make, I truly wish you the best.
