Ok, you are allowed to say you feel like that "right now" but as bad as today may seem, you "can" actually have better days. And honestly, there are a lot of 17 year olds that feel lonely and even "low" too. I had those days, I remember back then, but that has a lot to do with the age you are right now too.

My nephew really struggled when he was your age, actually right through high school and even at first in college too. BUT, he finally found his way, is very in love with his wife and is a very happy man right now. So, moral of the story is at 17, you really should be counting the "value" of life as you are, maybe at this age things are depressing etc, but, your life can be totally rewarding and different in a few years.

As far as your sibling seeming not to care? My guess is she is probably at the age where the norm is the "all about me" and that has no baring at all on your true worth. And you think you are "ugly"? Well, give yourself time, 17 is an awkward age and a lot of girls tend to think they are not pretty enough. Well, you could be "pretty enough" to some one else some day and end up having an amazing relationship. Believe me, you are going to grow and change a lot the next 5 years, so "patience" through these difficult times, patience.
