You can't move back without deleting your current account and starting over with a different user name, and even that's kind of frowned on.
Don't worry about what others think about your ability for your Tier/Level. If you join a decent club you'll be able to explain your situation.
And look for a club that uses Discord as a method of communication. That way you can chat away without any need for typing or transcribing into in-game chat. You just get set up with headphone/microphone and go into your club's server, jump into a Voice/Video room, and then you can chat real-time with whoever else is in there, just like you're sitting right across the table from them. You can also share your WGT screen, or watch someone else's if they are streaming, which is nice if someone better than you wants to give some live playing lessons. Feel free to take a look around Grand Traditions CC. We use almost exclusively Discord for communication, play Turf War and Clash (but no one is pushed or required to play anything they don't want). We have several season long events similar to FedEx Cup, play club vs club matches against other clubs, and always have a variety of free to enter tournaments ongoing. You can send me either a Discord or WGT Friend Request if interested and we can get you all squared away.
And you don't need special equipment or expensive headphones/microphone. I use a set of Airpods to chat through my Windows 11 computer, but as long as your computer has Bluetooth built in any old cheapo earbuds from Amazon or wherever will work just fine. I have a pair of earbuds I got off of Amazon for about $14 that work every bit as well as the Airpods, the battery life just isn't quite as good.
