Thanks for sharing. I work in the language that's not my mother language and often my train of thought would not be followed by correct words or sentence structure and that made me feel less worth and bad before. But then my boss told me that it's not big deal really and to just speak and learn from mistakes. He also told me to take it slow. I listened to his advice and my whole world changed. Hope this helps.
There is nothing to be ashamed of. I can identify to some extent; I dropped out of high school and got a diploma waaaaayyyy later...But heck yeah! Good going on getting through the three. You are totally going to ace that last one! ๐
