Depression getting worse from failing my class...

I am failing A and P by 5%.

I have to get a 78 and am at a 73%.

I had a really tough semester. My dog died, I got cheated on, and my grandma died.

I also dated and shouldn't have. I also went to 3 parties and shouldn't have. I also didn't know how to study and didn't take it seriously.

I am getting a 97% in oral communication  (speeches) and a 95% in developmental psychology.

And because of my depression (childhood abuse and rape) I feel like a failure. And then I feel overwhelmed from what grade I am at and then I am more depressed about my grade.

I already got accepted into nursing school. Should I drop this class and get an F in it and switch to LPN (don't need A and P and would start clinicals next semester instead of in 2 years for RN).

I really want to be a nurse and feel like obtaining my LPN and going back to school for RN later would be best for me rn.

I really cannot do this anymore... I am extremely hard on myself. I know it is only 5%, but I just cannot. My depression is getting worse and worse because I am so overwhelmed. I just need to quit this class right now and restart it next semester. I am so stressed and at my limit. I overdosed Jan 2016 and this one class is making my depression spike. I hate myself for not doing better in the beginning.

I feel like I am drowning.

I just feel like ending the class right now. Could they put down a withdrawl due to medical reasons (severe depression) rather than a fail?

Would educational support be able to waive the F grade for dropping it? It is only 20 days past the withdrawl date...

Is this a stupid idea..? I am 19.
