So the other day we had to take my sister to the Er has a bad concussion and pulled muscles but I texted my best friend about it and she went on about how she had concussions and never went to the Er I kept on saying it’s different but she kept arguing I don’t know what to do I was there for her when her dad died I was the first person there then I just text and say “hey Otw to the Er my sister got hurt“ and then her not caring and talks about herself I can’t drop her even if I wanted to she’s been the best friend I’ve ever had I got depressed and started to go to Wrong thing and she was there I don’t know what to do anymore advice??
