Get to the chaplain - today. Army chaplains are trained counselors. You can vent in complete confidence so long as you haven't broken a law. If you've broken a law make sure the chaplain's a catholic priest

. The chaplain should be able to turn you onto the army spouses groups in the area. This is a time the army family proves its value, T-Girl. Use it.
(Just in case you are that "type", take the time you would were going to use to tell me how uncomfortable you are with strangers, and instead, read your first post and think of a better alternative. It'll save us both time. :p )
Oh yeh, and call your mom. That usually helps some.
