There's no need for the attitude.

It's a shitty situation with no good options. You presented your option as obvious and straightforward. It's not.

OP has limited resources in the UK as she is not a citizen. She's on a clock too before she gets deported. She'd be burdening her family. And her problems would be worse than now when she's forced to return.

You can "if it were me" all day long, but this isn't a thought experiment for OP. She does not have the luxury of being allowed to be ignorant of consequences.
