Coming off disrespectul

Coming off disrespectul My mom raised me with good manners and my heart and soulalways know the right response but its so frustrating man when i block on saying thank you so much when people hold the door for me compliment me, or even after leaving checkout lane. I wouldnt even consider my stutter that bad which is annoying id say im 65% fluent. But when i do block i just either look really stupid or disrespctful and it maes me feel like a sub human somtimes i swear. Just came here to rant but we all gota remember life is precious being born at all is a gift.
