Not feeling loved is a symptom. I don't know about your life, but you're loved at least by the people here who read your post, and probably way more people than you could imagine irl. Have you felt love for other people before? People feel the same way about you. There's no one ever who has actually been completely unloved. There are people who love Ted Cruz. It's probably easier for you to imagine people loving Ted Cruz than it is to imagine people loving you, and that's a symptom. People feel solidarity with you too, not just love.
