Wtf have I done

I've literally been crying for the last 2 hrs about my decision to take part in a 2yr science course. I really really don't know what I want to do when I'm older and am completely lost with the course because I come from a very very low budget school and don't know half the things my year are talking about.. I just want to earn money but I have no job and need to get a levels over by the time I'm 19 if I want my uni plan to work :'( I feel really hopeless..I just needed to vent
