I’m so sorry to hear that you’re going through this- it makes me really sad. I have Tourretts and didn’t get diagnosed until I was 30- my whole life I had to try my best to try and hide this thing, and had no idea what it even was. I didn’t really understand how certain drugs/alcohol made it better and worse, I just didn’t understand it at all. Now, I have to rely on medication to help my symptoms and anxiety is the main one. I understand if that’s not for you, or if it would even work but I know there are new treatments coming soon that may help. I am hopeful about that. I also know that there are videos on YouTube that are kind of like speech therapy- not the same as the real thing but maybe worth a try? I really hope you are able to overcome this and have the career you want! I believe you can do it, don’t give up!
