Is the use of "state" correct here, please?
"My cousin is badly depressed. He drinks a lot of alcohol and refuses to work. He is in a terrible state. "
He's in a terrible state.
He's in a real state.
He's in a right state.
He's in a bad state.
He's in a really bad state.
All of the above are ways of saying the same thing.
Note that you don't have to use "of alcohol". If you say "He drinks a lot ..." people will know what you mean.
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
