Why do I feel pressured?

My best friend REALLY wants me to go to this event. Her mom doesn't want her to be there by herself so my friend is trying so hard to find me a ride go take me home. Don't get me wrong I wanna go but the event is from 5pm to 9pm and I would have no ride so my pops said for me to tell her to go another time. She really really wants me to be there and also my other friend invited me to a shopping day the next day and she won't be able to pick me up for that and my best friends cousin won't be able to take me to her house so he would have to bring me straight home. I can't do e everything! I'm going to cry. I appriciate her trying to get a ride for me but I can't take the bus at night. Especially way downtown. My dad and relatives won't be able to come get me.
