My mum says I am stalking her.. Please help?

She says to me today I am stalking her. I'm not actually stalking her.. How can you even stalk your own mother? We live under the same roof it's pretty hard to not bump in to each other! I feel like she doesn't like being in the same room as me. All she ever does is sit on her phone chatting to people.. She will need listen to ANYTHING and her reply is usually just 'yeah Mhhm' she's not really listening. I think she is too wrapped around all her so called friends because from day till night she is constantly on her phone texting, calling her friend and dealing with her friends problems and running around for her friend who uses her. She never deals with any of our problems, never really listens and of we do talk to her we are apparently 'stalking her' she said this because I was in the kitchen with her and I was talking to her' it seems as if she hates that! I see other mothers saying things like 'had a lovely girly night with my daughter tonight' but on a weekend my mum goes out to get away from us! She never wants to stay in. I asked her today if she wanted me to paint her nails with my new nail varnish and she said yeah.. So I say there for half an hour waiting for her to finish texting and then she said 'i can't be bothered.. I am Gojng to bed now, you can do it tomorrow' but as soon as her friend called her she got out of bed.. Why is she like this? I feel like I'm the least of her priorities right now.
