Learning is a consistent process and you will encounter  many difficulties. Should you give up? No,keep going. You will find a right way in the process of learning. With practices, I believe that your English will reach a high level. 

Today is a gift. Just leave all your sadness in yesterday. By the way, scores or grades in school are just a small part of your entire life; everything will be okay! 

In my opinion, the most important thing is to keep the passion for English, and it's also a good habit to help you for your different part of life. Trust me, I'm also a high school student who loves English now (maybe there are so many mistakes I made in grammar, but I am not afraid to try)

Come on, cheer up, everything will be fine. Don't worry too much and just keep going. You're the best.

It just a score, life is colorful, study is only a small part.

Take everything you faced today as your fortune in the future.

Nothing, nothing. I am a college student, and English is just like this. Spoken English is very poor. Learn slowly.

Forget the messy grammar rules; just remember that there is only one predicate verb in an English sentence.

Love it and just do it. Treat every single test as a chance to learn the English news and interesting survey. Take it easy to accumulate your knowledge of English. I'm sure that you will enjoy what you learn.😄

l think you are an excellent student, trust my judgment and also believe in yourself!
