Yes and no!!
The composition of tears is a complicated mix of chemicals and - or substances. The saltiness is similar to the saltiness of blood plasma.
Emotional tears are a different mixture - it surprised me to see there is a high proprtion of a natural pain killing hormone present. So they are right to say a good cry can make us feel better.
There is a lot of information about the different types of tears on this link.
