Personally I feel like if you view yourself as a loser then there's more factors other then your stutter. I hate my stutter and its annoying but then when I think abt my good qualities like being physically very fit for example I'm reminded that there is more to me them my stutter and that even though I stutter I have other good qualities that prevent me from being a "loser". The best way to cope with stuttering for me is trying to improve other aspects of my life, that way you never feel like a loser since you can say "even though I stutter I also am...*insert random positive thing here*. So if you do view yourself as a loser there most likely more factors then your stutter since there's plenty of people who stutter and who are the opposite of "losers".
