Hey Elderberry - I was going through this a lot during 2020 and into 2021. Sounds like anxiety (but I'm no doctor). Taking a quick walk outside was enormously helpful. Slow steady breathing in fresh air. Also if there's any way to get more exercise that could be helpful. I have no idea what your fitness level is like or how often you exercise, but when I was feeling my worst, 10-20 minutes jogging or climbing stairs or jumping jacks or anything was almost immediately calming. Also drink water! Seriously it felt like my body and brain were about to chew themselves apart but these fundamental health things worked for me. Hopefully you can also see there are tons of people out there who are willing to help and want to see you happy and healthy... maybe that's a little bit comforting as well.
