Mixed states are the worst. I have been in one for about a month. I know I was miserable.
Are you able to find anything to do, to distract yourself? Calming and soothing activities are good for me. Hot showers are my favorite when I am in a terrible mixed state.
It can be hard to remember to do anything good for yourself. Just try to calm, distract, and nurture yourself. You are worth it. Hang on, and know that this too shall pass.
