My housemate and I get on really well. We spend alot of time together and we are alike in a lot of ways. But we are also different in lots of ways. The thing is, I've adopted her whole personality and pretend to have the same likes and dislikes because I don't know how to disagree. I even speak and act like her.

Now I feel tired and sad because I feel I've become someone else and I've lost who I am, I have honestly no idea how to be myself or if I even have a self.

Just wondering if anyone can identify or give me any advice? Thank you
