It's really painful today, it will be a blessing tomorrow because she is showing you who she really is.
A blessing in disguise, I admit, but in time you might be thinking so too.

DO NOT watch sad movies, DO NOT listen to sad songs, DO NOT remind yourself, over and over again, of all the crap your mother might be into.
Think positive, ONLY positive.
Does it feel fake? Then, Fake it till you make it.

You are still thinking too much about her!
It's time that you start to think about you!
