3 month old son and husband to be deployed to Afghanistan in 8 days...please help.?

So, We just learned yesterday that my husband will be leaving in 8 days for Afghanistan. It's a 1 year deployment. As you can imagine, I'm feeling all kinds of emotions. I have a 3 month old son and we've been living with my parents for awhile because we've been having some financial issues. My point is, I have plenty of help with my son. My mama is absolutely amazing with him. She's always helping with him. I'm very lucky to have her. But I'm still so scared. I was sort of hoping that there are some other new moms out there that have dealt with or are currently dealing with their husband being over seas. I guess I'm just looking for some encouraging words. also, maybe some tips on how I can help my sweet little bear not to forget who his daddy is while he's gone. Any advice or anything would be greatly appreciated.
