I told my mom that i had made a topic stating i am moving to Vancouver, Canada.
I agree with what other posters have said here, but if the only personal info that you have given out is that you are moving, I don't think you need to panic.
Vancouver is a big place and I can't see how anyone could find you on the basis of what you have said.
If you or your mom are really worried, you could always post something else saying that there has been a change of plans and are moving somewhere else. Or, that you're not moving afterwards.
No one will know what the truth is.
Then, in future, be more prudent as to what you post.
