Emotional rant sorry

When I get into a fight with my s/o I feel useless and terrible. I was left as a child to my aunt and now my aunt could care less about me and now my s/o(who I live with) I feel like is caring less and less too now. I tried hanging out with a long time friend today and she left early with no excuse or explanation and when I looked over she sent a message to her ride saying that she wasn’t in the mood to do anything. I feel like everyone is slowly caring less for me and it scares me.
