I have a fear of the future, and it's only getting worse because of my grades. It seems that high school grades basically define whether you are worth it in life or not (according most of the adults I know) and when I think about it, I wouldn't be able to go to college in the future and the type of job/field I would like to go into in the future a requirement is college. And it seems (to my knowledge, I could be wrong sorry) that to even get a job you need some kind of education finished and I don't feel like that will happen with me. I was never a kid who really got good grades (I'm mainly in the D's and C's area, but I do get A's/B's in a class or two) and the past marking period I managed to get an F for the first time. My parents made a huge deal out of it and I ended up having a panic attack. I feel like I'm going to end up getting another F because I'm so terrible with Algebra and I constantly zone out in that class and don't understand anything and tutoring usually doesn't work for me.

Well, technically I am a freshman so I have plenty of time to improve my grades for the future, but for now I am still terrible in school and unmotivated, how can I make this better before it gets worse?
