Supposed to

But how am I supposed to put my kids through college?

But how am I supposed to pay for my college?

But how am I supposed to afford this?

But how am I supposed to find somebody?

But how am I supposed to earn a living in this place?

“How am I supposed to” indicates a rule / an established behavior that is followed / copied by the majority of people with no other reason than being part of it.

Now, did I question it? Did I ask myself those questions:

Do I really need to put my kids through college?

Do I really need college? / Do I really need college now?

Do I really needs this?

Do I really need to find somebody?

Do I really need to be in this place?
