You can typically tell if someone is suffering with anxiety, if you are, just by watching the little things that they do. Everyone has different little quirks that they do. Here are some of the most common.

1. Apologizing about everything, and anything.
2. Either standing and swaying, or sitting and rocking.
3. Being indecisive about making plans because they don't know how they are going to feel.
4. Playing with their hair, hands, or other objects.
5. Stumbling over their words when they are uncomfortable or embarrassed.
6. Walking away to "get some air" periodically.
7. Taking things personally.
8. Staying quiet, or having short responses.
9. Repeating themselves to make sure they either understand something, or have the right information.
10. Getting defensive quickly.
