Army wives i need some help please...?

my husband deployed in june he came home on leave and just went back on sunday. it was harder this time to say bye then last. i find myself crying all the time, not wanting to do anything, and felling like i cant function without him here. i don't know what to do i haven't been eating like i usually do. im not part of the FRG because we got married when he can home on leave so i don't have anyone who understands what im going through. what can i do to help me keep my mind in the right place and keep me sane?
