My roommate is copying me in daily things and it annoys me

I(22F) live with a roommate who is completely different from me , but I keep noticing that she is doing things the way I like to do . Those things are small but it’s like I am creating my own convenience and she is stealing my ideas . Some examples: I came up with this breakfast idea that is really fulfilling and tasty and I make it almost every day. Lately I saw how she is making exactly the same thing. I wanted to buy one specific type of tea pot and I was so excited about it that shared the idea with her. She was like “oh I also wanted the same” and bought it the next day. Then I had put this other type of chair for me to study with a pillow, the next day , she had done exactly the same. I am a morning person, she used to be a night person, now she tries so hard to wake up in the morning like I do and disrupts my morning routine. I go to yoga classes, she has never done it before, then a few days ago I see her doing YOGA at home . When I change my bedsheets , she does it also on the same day. I don’t understand if I am overthinking or not, but I really put a lot of thinking of my routine to be as disciplined, organized and convenient as possible and seeing someone copying pisses me off.
