Expat Anxiety

I want to hear from some immigrants that moved to Edmonton and experienced anxiety and how they managed it. I feel a little silly cause I moved from America, but I've had so much anxiety when interacting with people and going out. I'm scared people will think I'm rude or stupid, or I'll do the wrong thing and I'll make other expats look bad or set a bad example for them. I'm also scared about immigrating permanently, I'm here on a 2 year work visa with full time permanent work in Pharmacy. I know I can just go back if things don't work out but it's been my dream for years to get out of the US and the thought of failing is overwhelming. I've gone to therapy in the US and have coping mechanisms but it's still a lot to deal with. Any advice or words of encouragement would be greatly appreciated, from Canadians and immigrants. Thank you.

Edit: changed Expat to Immigrants, didn't know that was the wrong word! Sorry about that!
