Okay, my personal thought on this. You are doing exactly what
any teacher would expect of you working to make the assignment
the easiest on you. You had three assignments.

Turned in the first one. No matter the grade!
Have plans to get the second one in I'm guessing close if not on time!

The third is already started, you have 400 words. Have stated you know
you can get some more words written. I'm personally going to say maybe
600 more words is what you are thinking. So you would work to do that.

But that is still short the teachers requirement.

Honestly this is more than most students would put out to work through.
And many would fill in the assignment with lets say busy words and
sentences that have nothing to do with the assignment.

So I'm first very impressed with your thought and dedication to the assignment.
and second I agree you need to think about your health and go ahead
and drop this class.

I personally feel you are an superstar and definitely not an failure.

You have done more than most would even consider trying and then
needing to just drop the class.
