Trusting God when I'm scared

Yesterday TJ brought me to school, and I took his blood out of both arms (because I am supposed to get 50 "sticks" total), and he came back to pick me up at about 1:30 and so I was going to stick him again. He hopped up into the chair and I took his blood. For some reason this day the needle really bothered him, and he started to feel sick, and he kept saying he felt sick, and I asked him if he was going to faint, and he said I don't know, next thing I know his eyes are rolling in the back of his head, and he is making some weird noises, he was out anywhere from 30 seconds to a minute. Here I am crying trying to wake him up, and when He finally "came to" his whole face was white snow. For the rest of the day he was extremely tired, and not feeling normal at all. The weird thing is that he has already had a strep infection making every cut infected for over a month now. Odd things are happening, and believe me we are looking into what to do.

Last night I was worried out of my mind, because I don't know what is wrong with TJ. After we prayed for a while I layed in bed with a knot in my stomach, and TJ told me not to worry, God is in control of all things, and I had given God my whole mind and still that knot was there so TJ told me to go read some Psalms, so I went and read Psalm 20, and I declared that Jesus is my King and he dwells in my house. As I layed in my bed the literal heaviness that I felt was lifted off, and my mind was being filled with positive things, completely changing from what I was thinking and worrying about. God filled my mind with His peace. And now I have a choice to either accept that peace or worry. I am still struggling, but know that the God of the Universe is intricately involved in our lives.
