What should I do? I've been to 2 universities, 1 comm college, and a technical school? But nothing to show 4

I have finally figured out what I am pionate about but now I am paying on a school loan, and 1 loan with interest piling up, due to the fact that I went to school for what my mother wanted me to be, and not what I wanted to be. At the time I wanted to do military, but my mom discouraged me, she wanted me to be a nurse. I hate science and math. I love arts and crafts, and want to be an interior designer, but now I have a 15 mth old son, 2 school loans to pay back from wasting my time in school living someone else's dream. I was told I have to write to 4 different colleges to get my transcripts. This is quite a hle, when I told my grandma I thought about going back she criticizes me saying, "you have already been to school and didn't finish." My grandma watches my son while I'm at work. I don't know if I could pull the school thing off, she might not watch him if she knows, and I'm too strapped for cash to pay any daycare. Help, and dont trash me please! Can you give incite?
