It sounds like you tripped from the starting blocks. Its not terrible you didnt do well in school but Im sure it feels that way. When you're a teen there can be a lot more interesting things going on or maybe the usual subjects just didnt interest you. Thats not a good reason to hate yourself in my view but you started to then. Then mom and dad werent so supportive or at least they pressured you and you didnt have a direction to turn because you were distracted during the time you were supposed to be figuring things out. Still not a good reason to hate yourself but you did.

What if, while you're still young, you looked at a vocational school? You can get career counseling at a prospective college or trade school. You may not have interests right now but it could be because you havent been exposed yet to the thing that rings your bell. Explore everything.

I could encourage you to follow your dream but that may not pay the bills right now. If you're not socially anxious you might be good in sales. Lots of opportunity there.

What you've experienced so far has led you to believe you have no future but youre still at the starting gate. Its way to soon to give up now.
