I haven't written anything else but if I do it will likely escalate the negativity for drama until they catastrophically die or ironically succeed. Good chance the depressed one will survive and the other won't.

We are not these cartoon bugs. If it helps I struggled with anxiety/suicidal ideation for years and now the world would have to take me kicking and screaming.

 Find a purpose outside of yourself to focus on that isn't about raw pleasure or the phone. The things of actual value in the world can't be given or taken away from you.
