Today's been ok

I've been ok today. My parents took me out and about to get my mind off my pain because it's been making me spiral into a depression again. I've notice that I go most of the day doing just fine and feeling ok but then around noon I start to get extremely tired, my stomach starts to hurt, and I become really lethargic. I'm so tired of this pain. It hurts so bad and I can't do anything to make it go away. I just want to lay down and cry because I'm hurting so bad.
