You are sensitive to energies and picking up the clash of old and new happening in the world. It sounds like you are processing it on both personal and collective levels.

Be sure to get plenty of rest, self-care, meditate, anything that helps you feel grounded and balanced. It will be okay, you will acclimate.

Ah, covid I had it twice, it's not fun, but it does give you the space to practice self-care. Maybe you were pushing too hard before, and needed that reminder. Keep up with self-care long after you recover, it's important always!
