Do you think im being selfish?

Okay so about 3 hours ago I twisted my ankle really bad,and it hurts like hell where I can barely help but cry,but tonight my mom is having a party for her roller derby team and I don't want to ruin it so she's downstairs with them,and my stepdad is the bartender my middle sister is enjoying the party and my oldest just left with her baby(I was supposed to spend the night with her,but I got vibes she didn't want me too so I told my mom I didn't want to go)so I guess my question is ,is it selfish to be kinda mad at them cause they are paying no attention to me?I just kinda want someone next to me,cause I think it might be broken,I know this isn't dealing with LGBT but you people are a lot nicer :)
