moms??

I'm 16, and I know I'm old enough to take care of myself that's what I've done for a while now but I just needed my mom and she wasn't there. So anyways my mom is single and I want her to go out and enjoy herself and have fun. The problem is she came home and told me she was going to pick up some  good friends of ours from the airport at 8, okay go. She knew I already started feeling like I was really sick, then I finished up my hw and took a nap and woke up look at the clock and it's going on 1 then 2 and then 3, she's still not home and I have no clue where she is, I am calling and calling and you know maybe hey she got caught up with her friends whatever but by the time I called her for the damn 30th time just because I wanna know hey are you ok, but no and she finally answers my call and it's like are you kidding me all your going to say is it's whatever, I'm on my way home. Uh no your daughter has been extremely sick and needing her mom and yet no just go out and do whatever you want. Any moms have advice on how I should talk to her about this in the morning?, and sorry for the rant but I just think it wasn't right for her to do that tonight. Just your input because I'm really hurt. (There's more background to the story from the past , that's why I'm so upset.) thanks ladies.
