I don't understand why you think it's so hard to believe that you're worth whatever weirdness comes along with it? I mean, my life isn't any less weird or depressing than yours. I've been to outer space, and fought shapeshifting aliens who wanted to take over my planet. Then I was one for a few days.
The demons weren't you. They were the demon versions of you, but they weren't you, and I love you. Every thing about you, even whatever ugliness you think you're hiding.
