Struggling

I have been struggling so much lately. Struggling to find peace. Knowing half my family is on the other side of the world. Knowing that the process of bringing them home isn't going to be an easy one. Knowing that leaving to go get them means leaving my first born behind and knowing that will be even harder than I can imagine. So, as I said, I'm struggling. I try and cling to Gods peace and know that He is in control and I do know that He is, but it doesn't make this waiting much easier. I am a mother, and my sons are not with me. How do you find comfort in that? It is so hard but I'm trying....
