what is wrong with me?!?!

My parents just bought $500 tickets for me to go see ed sheeran a song writer I'm in love with. When they told me immediately I was like "ok, but I don't have the money to pay you back" and they said it would be a big present for my birthday, and they know I've been through a lot lately. But I just can't get excited. I want to but I just can't :(((((((((((
