I'm so sorry that you're struggling right now but am glad that you found SF as here you will find an amazing group of individuals who can offer advice, support and encouragement. Also if you haven't yet discovered it there is a live chat if you want to talk to talk to people in real time...so I encourage you to keep posting.
One thing that I found helpful was to break down the homework list into small parts so it doesn't seem so overwhelming which I remember it can be. I was wondering are you doing on-line or in person for school as know varies at the moment?
Please take to heart that you do matter and that you aren't alone as we are all here.
