Someone is ACTING OVERLY WORRIED OR FEARFUL
what YOU can do
Let them know that you notice their anxiety and that you want to help them feel better.
Discover the specific scenarios that make them fearful or worried. Do not minimize their fears and worries, even if it seems irrational.
Help identify things that help the individual relax.
Urge them to do perform daily activities even when anxious. Avoiding will be a momentary relief, but in the long run will make anxiety worse.
Strategize with the individual how they will use their calming techniques and what help they might need.
