How do I fix this?

I really don’t know what to do anymore. I’ve been sad before but it usually just subsides. This time it’s not. I spent a week in quarantine and admittedly I was sad before I went but now my thoughts are way louder. Everything is too much. I’m trying to make time for my school work but I can’t because I’m just trying to function while feeling terrible about myself. It’s so hard I don't know what to do. What can I do to help fix it. I can’t function like this. I’m trying to stay positive but I’ve cried over 5 times today. Im trying not to seem to sad around my family but they are irritating me also so I don’t know how to fix it.
