What you might do
Negative thinking and the feelings of sadness and worthlessness can mean you lose interest in the things you usually enjoy.
The things you are meant to be doing like school, work, university, even hanging out with friends, can all feel like a huge stress or chore. You might feel constantly tired whether you sleep or not.
There can also be changes in how you eat; you might lose your appetite or perhaps eat more as a way to feel better.
