Difference between with "do" and without "do"

Hi,

Could you please tell me the difference b/w the below sentences ?

" I want to see you "

" I do want to see you "

Hi, Pavan

The helping verb “do” amplifies the idea expressed by the main verb “want”. In other words, if you say “I do want to see you”, you mean that you want to see me very much
