I have a reprimand from the police and it's affecting everything!! HELP!!?

Every job that i would LOVE to do requires a CRB check and when it comes back i can't be employed because of my CRB check!! Please help. What should I do? Are there seriously NO decent jobs other than working in a shop that DONT require a CRB check. It's over domestic issues and it wern't even my fault! The only reason I got it is because i pleaded guilty cause I didnt want to go to court. Im only 18. I can't even get on some college courses.. Hmmm don't you just hate family sometimes.. :( Please help!!!
