"sort of" vs "kind of"

[Learning_English]

I sort of need help.

I kind of like that man.

Do you think the above sentences are correct? If yes, could you explain them to me. I haven't come across such sentences in my life.

This is correct informal language. 'Sort of' and 'kind of' mean 'rather' or 'in some way', 'to some extent'. I need help/I like that man, but we don't know exactly how much.
