Sure, you can talk to her about it. But I'm not sure what your expectations are? You can't make someone prioritise you, especially if they have actively decided not to do so for the past 10 years.

Honestly, you're 24 and at this point I think the healthy thing to do is just accept that your mum sucks and move on. I get that it hurts, but some people just have shitty parents. Them's the breaks.

You can cut her out of your life, if you think that will help you. Or you can continue this half effort type relationship, or you can blow up on her and hope that she see's the error of her ways. But that last one is more of a child's wish, and I don't think it's going to help you.

The best thing you can do is just let go of the pain, let go of the need for validation from you mother and just live your life.
