Is it bad/wrong l dont want to live as an old person? l want to die before l turn 60?

l am 16 years old. l have had many bad experiences in life l dont like people and they dont like me. l dont like living even now especially being in highschool which practically makes me feel suicidal. l cannot even imagine being all old and wrinkly espcially with my ugly face sagging and barely being able to do anything. l plan to see how life goes and want to die/probably commit suicide like at the age of 42. l also dont want to be in those nursery homes with other cranky old folks just taking meds and turning crazy and l would hate to see young people having fun especially since l have anxiety and cant enjoy life normally. is it normal to not want to live as an old person? does anyone else feel the same?
