I am so stressed out about everything: I have to stop being so paranoid.

There are many reasons why people don't answer messages in the first few days: business, mourning, tiredness, not having had time to read it, not feeling like replying right away etc.  I feel so weird these days: I had 2 weeks of mental health. I always feel a bit odd when it is the case. I become aware I am ill, way more acutely.
