Anxiety

I am so anxious and I don't know why. It's been since yesterday. I can't get rid of the feeling. I've tried reading scriptures, listening to good music, exercising, and I slept from 10:30-6:30 last night, so it's not lack of sleep. It's crazy! I've been depressed lately. I can't seem to get in gear and accomplish things! I am having a hard time not knowing whether our house will sell or not. I know i need to have more faith. I'm going crazy!
