Plenty of "normal" people (maybe all of them) still struggle with their own issues. I'm well-regarded as an expert in my field, I'd be considered successful by most standards, and I don't outwardly show any red flags around my colleagues. They probably assume I don't take any medication, because I don't exactly wear a list of my prescriptions printed on my shirt. They probably don't assume I work out, because they're not blind, but whatever. Little do they know that the only thing keeping me sane are a few tiny pills and probably way too much beer.

My point is, it's normal to be flawed. Everyone is flawed, and it's part of being a human. By comparing yourself to others, you're comparing yourself to the image that others portray, not to other people as they truly are. Compare yourself to version of yourself that's happy, and strive to become that person.
