Relationship with my mom

So I know this page is usually used for romantic relationships, but I need some help. My mom thinks she is the best person in the world. She doesn't get it when She is the one to make a mistake. It is never her fault for doing something wrong. There is always some other leading factor, whether it be an injury of hers or someone else. I love her and want to have a better relationship with her, but I have tried for 10+ years as an adult to take the high road and not argue with her, to take her complaints, and to let her do her thing. Now, it is very obvious that I am still not someone she Gets to be around but someone she Has to be around. It is small jabs like, never commenting on my FB posts, but always "loving" my sister's posts and always commenting no matter what topic it is; telling me last, at the last minute, about a plan I was invited to (because I am notified last minute, I often can't go); she remembers my sister's work schedule just fine (only been there 9mo) and can't remember that I start all my shifts at 2 (I've been working there for over a year). I have come to accept that she won't love me the way I want her to. So, my question is, how would you recommend moving on from the heartache of it? I am doing better, but I feel there is a part of me that wants to go back to trying to get her to completely love me, for ALL of me.
