<human>: Can you give me a shortened version of the text?

I am 19 and from California

About a year ago, I just turned 18 and was self employed selling things online. Even though I was profitable, my mom was extremely unhappy with this. She called me a failure everyday and said I was a disappointment. She only made me even more depressed on top of being stressed with my orders. She kept telling me to go to a Medical Coding School, so instead of just moving out which I should've done, I let her manipulate me into attending this school. I paid her rent $500 a month and paid for my own school which was $450 a month. Going to this school is the biggest regret I have. I only learned that I do not want to work in that field and I was very happy running my own online shop. I want to focus full time on my business and I am moving out from my mom's house. The only problem is that I am under contract to go to this school. They won't let me withdraw without paying in full from what I have leftover. I have $4k left to pay.

Is there anyway I can get out of this? According to the school, I attended around 65% of the courses even though I was absent a lot to work on fulfilling my orders (especially around the holiday season where I did not even go to school). The school said if I had only attended less than 60%, I would be allowed to withdraw. The school said if I don't pay up, they will send me to collections.

My mom signed with me but it is my name on the contract. It is her credit and name the payments are made under but it was me who manually paid for my own tuition. The contract states "You may withdraw from the school anytime after the cancellation period and receive a pro rate refund if you have completed 60 percent or less of the scheduled daysin the current payment period in your program through the last day of attendance" "If the student has completed more than 60% of he period of attendance for which the student was charged, the tuition is considered earned and the student will receive no refund" Any advice on how I can lessen this would be great, thanks.
