I live in America and I am from England, I dont know anyone here, so I have nobody to talk to either, and I get on okay, if you believe in what you are doing, and it's whats right for you, have faith in your self.
Having said that, mum's are often a lot of comfort and can be shocking in the things they understand, specially when they see it's something you seriously want/need, think about talking to her, it may help xoxox
