You can try one of the apps like Calm or Headspace or any other mindfulness relaxation app.Other ideas are reaching out to friends or family, exercising (not too strenuous), yoga.If none of these are helping, please reach out to your doctor who can give you a referral to a professional to talk to.You can also try reaching out to start with on the paid part of this platform and do a consult there.
