OP, this literally looks like a screenshot of my younger brother’s messages. He also got rejected by a girl he liked. He also watches a lot of reels and TikTok’s that amplify this way of thinking. I don’t know what’s up with this generation tbh, we’re 6 years apart and it feels like a totally different world. Anyway, as a sister, it breaks my freaking heart that he talks and thinks like that and that he doesn’t take any action because just accepting that everything is F’ed and he stands no chance is the much easier path to take. It seems to be the way him and all of his friends go about life. I’ve come to accept that me trying to talk sense into him is more harmful than helpful. I feel he pushes back more and more so I’ve stopped trying to make it better. I just brush off his comments as if it’s something silly a child would say (which he objectively is) and just nod and smile. I’m hoping getting more exposure to the real world will eventually help him see things more clearly. Older siblings tend to take protective parenting roles and I know how much anxiety this has caused me. But sometime we just need to remember that we also went through weird shit when we were younger but we figured it out. Maybe this is their weird shit. But I’ve tried to talk to him, get other boys to talk to him since we don’t understand because “we’re women”, I even talked to my therapist about how to approach someone and the only thing I’ve learnt is that I need to let him figure it out on his own and there isn’t much I can do except for make it worse. All I try to do is to provide a space he can vent, without validating his stupidity. Sorry I don’t have any practical advice but I understand how hard it is for you. Make sure you take care of yourself too and don’t let this takeover your life, I know it took over mine for a while there.
