Your mother don't hold bitcoin so she can say whatever she wanted to say and of course, she wants to discourage you. All time high's are coming unexpectedly so if you think that it will, it will. Don't think too much with what your mom said, just continue to hold and keep on trading bitcoin and as much as possible keep on holding it so no matter what happens you'll also rise when it starts to get back there.
I think that you can listen to your mother only if she understands the crypto currency market and bitcoin. Otherwise, most likely she will not be able to help you.
As soon as bitcoin will starts to grow we can see its new heights more then 20K$.
