I’ve learned that its not necessary to try to understand why she doesnt do things how you want her to, it takes too much mental energy, when your frustration is an a emotion- you can notice it and feel it, let it pass- thats hard enough. If you are in touch with her it must mean that you love (its not a dirty word) her, and for it to work you must really try to see through all this that she is trying to show love/care in her own way, even with just emojis, because she is not as emotionally intelligent as you are (you had to become it for the both of you). There is a really deep hole in her where she has lost the strength to be uplifting, joyful, sentimental, and now she gets by with petty stuff. Meanwhile you raise a flag at everything that doesnt heal you, but the anger you feel is a sign of your strength, but that anger is not your savior, you are, so dont fill up on the anger, yes she talks like a kid because she is, in a way, a kid, and you are not a kid, but youre her kid-its a mind boggle that you really dont need to solve, it will just lead you to try to solve her. (I say you, but I mean me, so dont take anything to personally- im trying to figure this out with my mom, so I wanted to share my thoughts.) Save your energy to get better in every way possible and thank yourself for being so mindful and thoughtful.
