My mom ignores me when I talk about my life?

I'm getting fucking tired of this.
Just now I just tried telling her about my plan to graduate early and she didn't say a word, just kept looking at her phone. I was talking for like 30 seconds and when she didn't reply I just said "okay forget it. " she didn't even react to that.

Another example was a few days ago and I was telling her that my best friend just got her first boyfriend and she looked at me for a second then went back to what she was doing.

And a couple weeks ago I was telling her how my friends just use me and don't really care about me and she just looked at me while I talked but never said anything. What the fuck.

AND YET she comes home telling me a hundred things about her day and I listen and talk to her about it even when its the most pointless, drawn out 20 minute story that I have heard before.

I don't know how to handle this situation. If I tell her I hate that she ignores me she will either ignore what I said or tell me I'm dramatic
