I don't even know why it's there. Yesterday I exercised and saw friends and that was great, but the moment I left the sadness rolled in and it's only been getting more and more intense. My chest hurts, I can barely sit up, moving feels like being underwater. I've no idea if this will last days or if I'll be full of energy and smiles in an hour. Its exhausting living like this, I can't seem to navigate the world around me because I don't function the way I need to.
