How do I tell a dnd group I want to leave? I'm DESPERATE ?

This DM is a first time DM and player. He ignores responses like "my character is scared, he runs to tell the party what he saw" and decides to run the game how he wants. He also mixes up a lot of information ("oh, the person turns into a creature and fights you" and an hour later "you still need to find and talk to that person") and doesn't fix it, just pretends it doesn't happen. He has a handful of issues and the party is unbearable. One girl has a working mic but still screams everything. Her normal talking voice is literally cut off by discord when she tries to say anything she's THAT LOUD. I'm going crazy playing with them. How can I GET OUT?
