<human>: Can you give me a shortened version of the text?

Hi /r/relationships. I'm a junior in high school. I'm a smart person and a good student, but admittedly I have a MAJOR time-management and procrastination problem. Which, ultimately, led me to fail a half of a credit of honors English. 

In addition to that, I'm failing algebra 2, chemistry, and AP world history.

My grades are not where they should be and don't reflect my abilities. I'm fully aware of this, it hangs over my head every day. I WANT to do better, and I'm chipping away at getting those grades up. I have a lack of motivation that I can't seem to get past, but that's another problem for another time I suppose. 

My parents don't understand how difficult school is for me. For someone who has no motivation to rise about mediocrity. I don't know why I can't do better, but at least I'm trying.

They (my parents, but even more so my mom) tell me all the time that I'm not getting into college and how much of a disappointment I am, and it's really hard to hear. I have diagnosed major depression and anxiety issues, and when they say stuff like that I become extremely volatile and very, very sad.

I've tried to tell them how I feel, but it's like talking to a brick wall. 
All that comes of it is screaming and yelling. It makes me not want to try anymore, then I fall further behind. They have threatened to "make my life a living hell" and not let me go to prom. What should I do?
<bot>: Parents are cutting me down emotionally in regards to my grades. Talking gets nowhere. How do I make my feelings heard?
