Allah will forgive all sins expect for the ones who expose their sins publicly. If i tell of my private sin to a close friend of mine. Only one person because i was seeking advice from him to get rid of the sins. Am i from the ones who are exposing their sins?

No, the one meant in the hadith is the one who boasts of what Allah covered and spreads it among the people, not the one who tells a trusted person privately in order to be helped out of it. Keep it to the extent that is actually required for you to get the help you need, and your repentance itself needs no telling at all.
