You can probably get therapy via zoom. So you are not limited to your town. Blocks are hard. Focus on gently approaching the "a" sound in Amy. Gently breathe out and hum a little if blocking and see if you can turn the hum into "amy". Also, practice. Start by calling places. They don't have to be in your town. Just pretend you are a potential customer and always start by introducing yourself. You can't really embarrass yourself too much because you'll never talk to them again.
