Emotional Rollercoaster!

I am not sure what is really going on here.  My emotions are all over the place.  I know that it is months before my DH leaves, but it is like I cannot even tell him that I love him without breaking down.  This is the first time that I have been through this and I am really not sure if my emotions are normal.  i feel like I am falling apart.  I did try to talk to the hubby about it this weekend, but I feel like he just blew it off.  I know he has to be going through his own emotions and I just wish he would talk to me about it.  I really need some support here and I feel like I am the only one that is going through this.  I need someone, anyone to talk to about this.  I am just afraid of falling apart.  I know that I need to be strong for my children.  I just need to find the strength.
