Me parece es normal que las personas tienen dificultidades del idioma diferente que sus lenguas maternas.
Tengos amigos Mexicanos. I was talking to one of my Mexican friends yesterday about this very challenge for Mexican Spanish people. I am Canadian and a native English speaker. As such, I have similar challenges when pronouncing Spanish words. It has to do with phonemes which are accent tones that develop in our brains when we are immersed in our native language.
It takes hard work and practice, but you can succeed. Keep your hopes up, find a native speaker to exchange conversations. Then, give it your all.
Buena suerte con sus goles.
