I'm a mom and I'm not sure if I should go to Culinary School?

I'm a mom of a 10yr old girl with autism and and 8yr old boy, I've been a stay at home mom for 10yrs, in high school I majored in art and fashion, I wanted to become a fashion designer and go to FIT in nyc but I felt to intimidated, so I decided to go to art school. That didn't last long because I couldn't afford it, I really miss doing art. Two yrs. ago I thought about working in a bakery, I worked in walmart as a cake decorator, and I really liked it, but they said I was slow, but they had no problem giving me a raise, and they wanted to switch to produce, and there was a rude old lady who was jealous because I learned quicker than her, and nobody liked working there but me and the head baker, so I left. So I thought about going to culinary school in the city for the Pastry and Baking Diploma so I visited the Institute of Culinary Education in Manhattan, I really enjoyed the tour and would like to do it but I live in upstate Ny, I can't do it during the week 'cause my kids are in school. They do have weekends but it's sat. and sun. 9-5pm and I won't get home til' after 8pm, and I have to do this for 8-10 months, so I won't be able to spend time with my husband and kids on the weekends, and I feel bad because he won't be able to do much either. Plus my mom won't be able to see the kids because she lives in the city, my husband doesn't want to spend all day with my mom, so that's the dilemma. So should I spend $26,000 on a loan and do it, or just take the individual cles at the school and other culinary schools, and If I take individual cles in culinary schools will I still be able to get a job in a bakery in the city? I figured If I took some cles I would be a little faster, I've looked at a lot of bakery positions and they do want you to have experience, so should I start out as a counter/cashier? and If I take cles how do I show it on my resume?, and should I show pictures of what I did in cl?, a portfolio of some sort? I would like to get a diploma to know I accomplished something, but do I really need one? I want to go for it, but it's so long to go without my weekends and family? Don't know what to do, any advice out there? Thanks.
