I am not sure whether posting to QL your concerns about your relationship with fellow Filipina is appropriate. I hope you understand that there are many readers in the site and posting something negative might create a not so good impression...
I think the best way to do being a good person as you said you are, is to talk to your roomate. Tell her everything..things that bothers you..about your need for sleep..your feeling that she doesn't care..afterall, you are living in the same room..be open..who knows, maybe she have her reasons..and maybe she will get and understand that she's not alone and respect your needs and privacy.. and then your relationship will be good again..if this will not work..then try to look for another place..it's kind of hard to live feeling terrible about someone specially a roomate..
