Bear

It isn't your responsibility to

Bear someone's problems on your back

Because they don't want to deal with it

Alone.

You don't have to let their negativity

Suffocate you.

You always have the option

Of walking away.

(Side Note: Of course you should stay and try to help someone if you can. But if it starts to become overbearing and affects you in a negative way, that's a sign you might have to walk away.)
