I wish I was never born

I somehow always felt like that but this year this feeling has grown out of proportion. Don't get me wrong I don't want to commit suicide, I just don't feel like I have a purpose here. I don't feel like I have motivation to do anything and I'm so lost when I think about my future.
I tried university this year but the more the time passed, the less I knew if it was a good idea or not. Was I trying out university because that would make my immigrant family proud or did I do it because that's what I want to do with my life.
I've always felt like such a burden because I was born into the country they immigrated into and didn't have to "fight" for my right to be here. I'm so proud of them for being who they are now, but I do feel like it set up a standard for me since I'm a kid. Since I was born here, I should be better, go to college, have a bright future, get into politics,...
I was always a very distracted and sensitive kid, I've always had the ADD symptoms but was never diagnosed or treated. That made me feel stupid and useless because I wasn't as smart or good as other kids. I wasn't as performing as my brother in elementary school and secondary school. That pursued me for so long and the more this feeling intensified, the more I surrendered to it. I have been feeling empty of purpose for so long, I don't even feel stress anymore, I failed my classes because it's so hard to keep up and still be motivated. The more I studied the less I saw the end at the end of the tunnel. Do I feel that way because of my attention problems? I don't know.
what i do know now is that I have to make a decision on the 10th about my future, if I decide to retake my exams at uni or if I do something else. I have been thinking about fashion school or photography major but what if the same happens? What if I'm not good enough to be anywhere?
In anyway, The last thing I want to do is keep disappointing my parents.
Is there something I can do about this?
Is there anything I can do to gain back my sparkle and motivation?
