She needs an outlet that is safe but also her own. Which I know is hard given the pandemic. Maybe online art or pottery classes? I went through this phase and my mom was utter shit to me, taking my door off the hinges when I needed a minute alone, snooping in my journals, never allowing me any type of privacy, screaming at me, etc. I never learned to process my feeling properly as a result. There's a thin line with teenagers, but showing them a little consideration is better than driving them to hide things. Also, emotions are 100% harder to deal with considering current events. You both probably need an outlet.
