So I'm 18 and my girl is a lot older. I fell for her hard, we were talking fine and then she worked double shifts. After that I tried talking to her but she gets mad. She called me lastnight and we talked for a little and I was nad cause she woke me up. After talking I sent her a kiss and she told ne she doesn't know if she wants to talk to me but she told me to text her tomorrow. What should I do cause I know she still likes me

Plain and simple - grow up and stop the drama.

Obviously she has not fallen for you hard. Now before starting a relationship with you, you throw drama into it by getting "mad". Regardless of the reason that was just not your best move. She is thinking "Why would I want a relationship with this person?" Drama is just stupid. If it were me and you were already doing this I would bolt quickly.

She is probably thankful you showed your true colors already.
