A bit of background; Someone I know told me, sometimes they feel crazy 'cause there are just so incredibly many different narratives and stories in their mind, about all the relationships they’re in… they forget who they are themselves sometimes, don’t know what to trust and believe so they feel very overwhelmed. Like, they want to trust, but who/what to trust in?

Which storyline should they align themself with, again?

Or, how can I help them? Maybe not engage in their irrational overthinking, but rather lead them help ground themself by taking care of their physical needs first? Sleep, water, food, exercise, etc

Serious answers please. Thankyou!

Edit: also, when those needs are met, what topics should they nurture their mind with to grow their mental health?
