My therapist once said:
The reason you're staying in bed for hours without sleeping, wearing the same clothes for days, and craving isolation even when you feel lonely is because your body is coping with overwhelming stress so it's shutting down to save energy and create a sense of safety.
If you needed to hear that, maybe this account can help.
De pequeño no entendía porque mi padre a veces estaba en el salón en silencio. A lo mejor nos acostábamos todos y él se quedaba en el sillón un rato sin hacer nada, solo estando. Ahora lo entiendo.
