I feel so bad for my fiancé on days like today. I live and struggle with severe depression. Some days I wake up feeling like I can conquer the world, other days it physically hurts to get out of bed. Today has been one of those days. He thinks I'm mad at him and I've tried explaining that I'm not and I just need to be by myself for a while, it's self therapy. I wish I could be a normal, genuinely happy person.
