It is the Orthodox understanding that such manifestations as you mentioned can be spiritual from God or can be psychological or can be spiritual delusion from our Enemy the devil. It is certainly not for me to deny any genuine spiritual experience with which God has blessed someone. My difficulty can be to separate between varying experiences. As a rule the Orthodox approach is one of caution and wariness. We do not deny spiritual gifts - one can think back to the great Russian Saint Seraphim of Sarov who was gifted with miracles by God, or from our own Coptic Orthodox patriachate in the middle of the twentieth century, the previous patriarch His Holiness Pope Kyrillos VI who was granted gifts of healing and prophecy for example. So yes such gifts can be true and most certainly from God - but we must also be aware of the possibility or prelest or spiritual deception. There is such a thing as the gift of tears and Bishop Kallistos writes of this in a chapter of one of his books so I do not deny that you experienced this - but I cannot be certain that it was not psychological rather than a spiritual gift. The excitable style of some Christian worship can certainly lend itself to psycholoogical effects.
So I cannot tell exactly what you experienced and am in no poistion to give you any definitive judgment or dsicernment on this. As a rule though Orthodox emphasise sobriety rather than excitement in worship. Our experience of God is more that of the still small voice rather than the earthquake, wind and fire - though we do know how to shout Christ is Risen! and to thoroughly enjoy ourselves at Holy Pascha as we celebrate the Resurrection. We do have feasts as well as fasts in our Church year!
I have, by the way, posted another sermon into the Education section,
