Too long, but God's still working

I haven't learned everything God has in store for me to learn. The past couple weeks have been really hard on me. Really, really hard. I don't feel like myself. I'm stressing beyond anything I've ever stressed before. Even when Daniel didn't have a job. I'm sure part of this has to do with my thyroid, but anyway... everything is getting me down right now. I've been insanely stressed over money right now. How ironic is that? We both have jobs and now I'm still stressed about money. Did I seriously not learn my lesson last time? I know in my head that the Lord is going to take care of me, but boy, something in me is going crazy. So I think God decided He needed to give me another reminder of His goodness and loving kindness. I've been worried about all the costs associated with the house we still own. We have someone paying the mortgage, but the taxes and insurance fall on us. Also, we have an $8000 tax credit on the house that needs paid back in a couple months. I could not figure out how in the world we were going to do that. This morning I woke up to an email from the lady renting our house. Her old house sold and she had started the paperwork to purchase our house. It was like God hit me in the head (again!!) and said, "Hello! I'm still taking care of you!" So for a little while, I felt great. But then all these doubts started creeping back in. About crazy things. I don't know what's wrong with me, but I'm back to the minute by minute process of telling myself that God is in control and He continues to take care of me. I guess that's where I need to be! I just can't figure out why I can't get it through my head!
