Titanic, you say you're "Asian"; do you live in Asia and have a problem with pronouncing L's and R's?
I was born and lived in Vietnam for 6 years before moving to NYC. I have no problems pronouncing most words, I still have a slight accent when pronouncing some words. Vietnamese is spoken mostly with the back of the tongue and the throat, so if you pronounce the same spelling different, it has a different meaning.
Ex: the word La
La (pronounced with an "a" like in the English word "car" means to yell)
Lá (pronounced with an "a" like in the English word "fast" means "leaf")
So when I began to speak English, the words that made you use the tip of your tongue were hard, "love", "tranquility", "rover", by now I have no problems because I came here at a young age. My parents have an extremely heavy accent however. I still sometimes mess up a word if I speak too fast, I can't do tongue twisters at all. But my grammar and spelling is, tbh, better than the average person my age because I spent most of my childhood learning English, and I only had one year of ESL class. The rest developed from playing games and watching TV shows.

My American friends tells me I also have a slight NY accent as well, like the word "water", I say "watuh".
