I’ve had a really hard time with M and B. I used to live in a town named Middletown and if I had to introduce myself and where I was from I would get so anxious. Instead of saying “I live in Middletown” I’d say “Middletown is where I live” because it was easier for me. Same with the letter B, I used to dread at restaurants if I wanted more butter. Either I wouldn’t ask or I’d say something like “Can I have more of the…butter” which helped. I’m better now because I try to say phrases as they should be said instead of switching things around. It’s hard but the more you try the kinda easier it might become.
