Why do I fear?

So for those of you that do not know Jeremy has been working out of town lately. I am a big baby and do not like being a lone at night. I end up really barricading myself in and do not sleep well because I am so scared. As I've been going through the study Believing God by Beth Moore I've come to realize that if I am so afraid then that means I do not believe God can keep me safe. I am not trusting Him but instead am scared laying in my bed thinking of all of the horrible things that can happen. Why do I do that to myself? So last night I barricaded myself in my bedroom and got in bed and just prayed that God would give me His peace and security. Anytime I began to feel afraid I just started listing all of God's attributes and really focused on the powerful ones like Mighty God, Strong Tower, etc and it really helped! I ended up sleeping really well until my cat decided he would cry really loud until I let him in the room. I'm going to start focusing on how powerful God is and not focus on being afraid. I have no reason to fear....God is right there with me and will get me through any situation I come across!
