Those lyrics are pretty harsh and would be a really low blow if she did set that song to start when you woke up.
Focus on you and try not to let it get to you. I also wouldn't say anything to her but that is just me. I have been dealing with my sitch for only 4 months so don't have much advice to offer.
However, stay strong and take it one day at a time.
