Trying to stay positive

It's getting harder and harder for me to keep my head up. I thought I was doing a pretty good job of staying positive or at least appearing to have a positive attitude but once again, I am wearing my emotions on my sleeve. George called yesterday and said, "I talked to your dad today. He said you were being mopey. Stop being mopey." I thought I was doing so well! It's hard lately. It looks as though the house is not going to happen. I know that God is saving us from our first big mistake in life but this whole process drained me and now, we have no place to live. I'm feeling like a single parent. Isaac is starting to sit up a bit and is making large strides toward crawling. I think he may have gained a pound or two as well, not to mention he's started sleeping soundly through the night. Chrissy is stringing together her own sentences and has figured out how to use doorknobs and zippers. I'm proud of my two little boogers but I hate knowing George is missing out on all of it. I haven't been married that long but three weeks without my husband has been a tortuous eternity. I can't explain it but it feels completely unnatural to be without him. I'm also pretty isolated here. I don't have the means to get out (I can usually use the car one day a week) and even when I do get out of the house, it's to buy necessities for the children. I don't have friends to meet up with and I miss my friends back home terribly. I hope they know I miss them because I haven't had the chance to get on the computer and tell them as much. Other than my cell phone (which only receives calls from George and my mother), I'm completely disconnected from my world. I'd give anything to see my friends again and I'd probably cry if I could see George for at least a few hours. I'm in desperate need of encouragement and I feel myself doubting God and his plan for our life at the moment. I'm having a hard time taking solace in Him and I feel that I'm a very weak Christian. Oh, dear. Where is my sunshine?
