Im lost and confused

Here goes nothing, I’m 16 years old and for years I’ve struggled with life I guess you can say. I’m spoiled I have four loving parents and five loving siblings Im a captain of 2 varsity sports teams im in symphony for my instrument I make straight As know what I want to do in the future but I don’t have a want to live I’ve tried to kill myself many times and it’s a thought I battle everyday some days are good some days are bad some days awful I feel unwanted and unloved by everyone even my family my parents yet I know they love me when they found out the first time about my suicidal thoughts they threatened to take everything away which only made the thought of going to them for help a 0% chance two of my sisters seek treatment for depression and anxiety and I feel stuck in a bubble of loneliness I tried to overdose on Christmas I wanted to go in a quiet way where no one would notice no one noticed I wasn’t around where everyone else was anyways this is just a grain of salt compared to what I’m trying to say I just can’t find the right words I just need the right words!!
