I had a lot of rejection all at once. Career rejections, love rejections, one after another. Life's just like that sometimes. When you end up in situations like that, you can get a lot of intrusive thoughts about your life and your value as a person. A little voice starts creeping into your head telling you bad things about yourself when you're trying to sleep at night. I eventually got so worn down by this I just started having mental discussions with these negative thoughts instead of shoving them aside.
