I'm sorry that your mom is not being supportive or encouraging - that has got to be tough. Hang in there and keep following your goals/dreams. High school is compulsary - you have to go and the environment is not always supportive for all students. College is optional - most are there because they CHOOSE to be there. Its ok that you currently hate school, you probably hate that it is not of your choice and might not be supportive for you. You are choosing college - big difference in outlook.

Hang in there, you are on the right track.
