Creep

The song describes exactly what many socially inept males go through when they attempt to hit the dating scene or look for love. They have feelings of insecurity, unworthiness, entitlement, low self-esteem, anxiety/fear, etc. Not being able to make good eye contact, check. Putting beautiful women on a pedestal, check. Coming off awkward when trying to reveal their intentions (usually sexual), check. Being negative and not seeing the positive attributes that do make themselves special individuals, double check.

Many of these guys don't have an internal locus of control and compare themselves to others. They attribute their success in life to outside forces (fate), rather than taking responsibility for their own successes and failures. They fantasize about how good other people have it and that if they only had money, or good looks or a better personality, they would be able to get what they want in life (namely sex with women or a romantic relationship). You'd find these guys on social media looking at the highlight reels of other peoples lives, doing fun things, being happy and thinking that these people (usually old high school class mates and friends of friends of friends) have it so much better than them.

When Thom says "I don't care if it hurts", I picture this is where the forever alone gets to the point where he is fed up with being lonely and decides to do something about his predicament. Unfortunately, being a social and/or dating novice makes this guy a complete bundle of nerves, uncomfortably awkward, lusting over the possibilities, only looking for specific outcomes and coming off creepy, depressing, and unfun.

However, on the positive side, it takes this kind of awkwardness and getting out of the comfort zone to learn from these experiences BUT many guys lose hope after being rejected due to coming off like a creep, hence the chorus "But I'm a creep, I'm a weirdo, What the hell am I doing here? I don't belong here"

This also brings to mind the idea that these guys start on a self-help journey of sorts. They go to the gym ("I want a perfect body") and try to read philosophy on dating, success, spirituality ("I want a perfect soul"). These things are all well and good, but it still comes from a place of not being good enough, that they are unworthy until they obtain X amount of money, Y amount of knowledge/skill/experiences, and can lift Z amount of weight on a barbell.

What ultimately makes a creep a creep is fear and their intentions. If a guy is afraid to put himself out there, doesn't like himself so he hides away (becomes shady and pervy) and only has his mind set on the outcome of what he desires (in many ways objectifies women and love), then yes, it creates a persona of self-defeat and repulses everyone away.
