>I also got so tired of stuttering so much I just spoke all the time regardless of the outcome but have mostly just been singing and repeating lyrics of songs I like accurately for 4 months, dunno if that's important. That should be major part of the reason. You stopped caring about stammering, so the anxiety went away. Obviously, you're still not 100% fluent, afterall it's years of learning + there must be some neurotic component.
