OMG YES ME TOO!! but what i find helps is, either using a nickname for yourself (i'll shorten my name to sam and for some reason i find it to be much easier) or like some other commenter said, insert your name into a sentence when introducing yourself. something like 'oh my name? my name is ___'. as an aside, i have trained myself to increase fluency with a metronome. now it is not feasible to have a metronome with you at all times, but the concept is still the same. whenever you find you need to say a word that is particularly difficult for you (for me, it would be something like 'productivity';, anything starting with a 'pr' sound), i tap my fingers against my leg or something as though they were a metronome and match the syllables to the pace of the tapping, if that makes any sense. something like pro *tap* duc *tap* ti *tap* vi *tap* ty. hope this helps! :D
