I wish I feel like my sister cared like I still meant everything to her like she does to me I wish I felt like my sister cared

I wish I felt like my sister cared because whenever I try and talk to her she remains expressionless like nothing I say matters but then we can talk about her and what happened at work and her friends at work and the she guy likes and suddenly she's the most happiest person on the planet our conversation always comes back to her friends at work and the guy she likes and I'm just so sick of hearing about those people because she's making me feel like I don't matter to her anymore I know I probably feel this way because my medications not working but there's never been any single thing that proves me wrong about these feelings nothing nothing has ever proved one in my mind when it comes to this so when the my mind tells me that my sister doesn't care that my words don't matter to her anymore it cuts the deepest because I have no proof that it's not true I have more meaningful conversations with my brother than I do her now and that hurts because she always used to be the person I would talk to and we just sit talk about everything we would understand each other and I feel like she cared the most but I don't anymore I really wish I felt like my sister care
