People who call others losers are often losers themselves. I find this "better than you" mentality to be ridiculously childish, no one is better than anyone.

People are just more privileged than others, doesn't make them a 'loser' because they aren't as ever so AMAZING than someone who has a massive ego. Just means you're not an idiot who feels the need to put others down less fortunate so don't worry about it. There's plenty of people way less fortunate, does that make them losers or does that just make them less privileged? Not everyone can be this pillar of egocentric amazingness afterall. Frankly I'd prefer to be the latter if it means I don't have to deal with fake egotistical people like that, they are the real 'losers' imo. Most people don't actually like people like that they just hang out with them for social status anyway.

People who fling that derogatory insult around don't value you as a person, a human being, so for you to use that term on yourself it speaks volumes that you don't value yourself either and that's not a good thing, I'd suggest you start by stopping calling yourself that because it's an idiot word and you seem far from being an idiot OP. You deserve better, like everyone else.
