Can I use Feeling Hungry and Feeling Sleepy?
I am feeling Sleepy.
I am Sleepy.
I am feeling Hungry.
I am Hungry.
Which ones are correct and Why?
In some other cases, there is a difference in meaning.
"I'm feeling sick" sometimes means "I'm feeling nauseated"
"I'm sick" means "I'm unwell".
If you were feeling faint, you'd say "I'm feeling faint", not "I'm faint".
Then there are cases where you have to use "feeling" because otherwise your sentence wouldn't be true. eg. You win $20 in the lotto.
"I'm feeling rich!" not "I'm rich" (which you aren't).
By the way, in all these cases "I'm feeling ... " can be replaced by "I feel ...", and this is more common, at least where I come from.
Is this sentence appropriate?
You are sounding tired.
