feeling awful

gosh I was sitting watching tv and this horrible sadness came to me and I have no idea why. I feel like crying but i dont know why. I feel so tired and cloudy. dont know whats wrong, I just am feeling so much like i want to stop and give up. I dont know why I just know I do. feeling so alone. so lost without purpose. dreaded next week being at the bible school, i want to i always enjoy it but the thought of going some where everyday seems impossible at this moment going to go lay down
