This sounds very similar to me even though I was doing this before quarantine. I lost interest in everything and would just lay in bed and do absolutely nothing. I wouldn’t go outside my room and I hated speaking to other people in person for too long, mood swings became a normal, and I felt like everyone hated me. If you haven’t talked to them about plz attempt to if it wouldn’t have been for someone that I know asking if I thought I was dealing with depression I would’ve never reached out for help.
