Anyone has a super cry baby ?

My son is 6 weeks today . He is an extrem cryer. He eat a lot we bath his after every duper change , we give him gripe water, rock his , hold him, play him claiming music , take him to the fresh air at the balcony , give him love, breastfeed him but he just won't stop crying . I worry something is wrong . I worry something bothers him but I don't know what ! He stays awake for 2 or 4 hours , he obviously wants to sleep but just won't ! He is very tired but he won't sleep . He cried so much .
