Hi.
Your very last sentence says a lot about you....
You don't have to be that person here. We are not judgmental, at least I have never found anyone here to be. You can say how you feel because it's how YOU feel. And we read because we WANT to read, not because we feel obligated.

17 is difficult. If you can get through high school, you can get through anything in my opinion. And you do have the opportunity to finish, I hope. Perhaps in the near future.
You would find college to be very different. I know, I have four adult children.

As far as your question goes, the mom in me is having a difficult time not responding as a mom.

I will tell you that it's important to cultivate whatever it is that makes you unique. You don't have to be good at it, you just have to love it. If you think you have no talent, look again. At 17, you haven't had time to do it all in order to find any really...
And many many things are achieved, not because someone was good at it, but because they persisted. My youngest has no musical talent, but he loves the piano and is able to play a tune or two. He learned that. My daughter discovered a love of animals and so she volunteered at a bunny rescue.
The other two also have things that they do that enables them to be unique. And they all know that beauty fades, but a sense of humor never leaves you.

This sense of uniqueness is, in my opinion, a very good self-esteem builder.

I find that we can never see ourselves from the point of view of another. So even though you think you're being as objective as you can, you're not.
And (this is my own personal opinion) I think that women are not at their most attractive until their 30's.

I sincerely hope that you keep looking for your own signature in life. Try lots of things. And never say never.
