Confused on how to make a model

I am new to Scholars, and have an issue I would like to make a model for but I am unsure how to go about it. I have been a SAHM & homeschool mom for many years, and this is the first year I am no longer homeschooling. My oldest (18) started community college this fall, and my youngest (13) is attending a Christian school this year. I am home during the day, and am not sure what to do now. I have a small Ebay business that is a side hustle, but is not something I want to pursue full time as I am not passionate about the work. I do not want to pursue a full time job outside the home, because I need to be available to drive my son to and from school every day (1 hour round trip every morning, and every afternoon). I want to be productive doing something that matters to me, and not waste the time, but I am not sure what or how to figure it out, and I often feel stressed because I don’t know what direction to go in or how to figure it out. I would really like to do something that would lead to an income as I am currently separated, and will most likely need to support myself. My thoughts are all over the place, and I often feel overwhelmed and stressed about my situation. How can I plug this into a model, and what would that look like? Thank you so much for your help!
