I hope you try to have a good birthday.
Regardless if you think you're special or not, or if you said that as a joke, I think you're special. Life might be getting you down, but my advice, did you really expect to have life by the reins by 17? Take it slow, man. It'll come to you later somehow.
Whether or not you believe you have the potential in you that I see is only for you to decide, however.
