Anxiety is being unable to get out of bed in the pitch dark night to go to the bathroom. Anxiety is being unable to go down the pitch dark hallway to turn a light on.
Anxiety is this unknown feeling running through your body just because you have to talk to a store associate to find a product you can't leave the store without.
An anxiety attack can leave you feeling like you ran a 5k marathon without moving an inch.
It's not an excuse. It's an invisible wall. It's not easy to pretend, because anger and frustration can easily overcome a person. The visible shaking and color gone pale can't be faked.
Sometimes meds can't fix it. Sometimes it can't be managed with a therapist. Sometimes it has to be something you learn control over.
