Please elaborate does the use of social media to getting news/status of patients in the covid-19 pandemic increase depression/anxiety? is the stress/anxiety caused by lockdown?

Pandemic anxiety: For most people anxious or depressed because of the pandmic, there are multiple causes; maybe best not to focus on only one. If you feel worse when you access pandemic information by social media, it's an important aspect for you. But other factors may be contributing, like nonstop news about the pandmic, politics, or simple loneliness. You're not alone! Try to relax, reach out to friends.
