How fix a problem between me and my mum?

Hello!

Basically it sort of started on Thursday.
I don't know what I was thinking, but I didn't seem to care at the time when I got told by my mum that she wanted me to stay at their house over the weekend.
This, because she was in tooth pain.

I could quite possibly gone up to my boyfriends house from Friday up to Sunday night.

My dad then said “why don't you come back for Friday night?”
I sighed and then went upstairs to my room.

Then Friday night I was being really horrible to my mum by saying things.
She was still in pain then but all I wanted to do was go up to my boyfriends for the weekend.

My mum was really surprised to how I acted, and said this wasn't like me
That I was like a completely different person.

I really can't believe how I was so nasty, when all of the time she has cared for me day and night, all hours!
She has even got up early for me to care for me.

I got home tonight and she said how do I know if you would care for me in the future, and saying how she doesn't know if she should care for me anymore.

I really want to fix it but it's not like I can go back and change it....I feel like I have wrecked what they think of me :'(:'(:(:(
