Career mom

I’m at 28 year old mom and my kids are officially back in school and I thought it’ll be a great time for me to go back to college. I’m extremely embarrassed because I don’t have a career and very unsure with what I’m passionate about. I loved animals growing up but ended up having bad allergies so I can’t work with them. I’ve always worked In retail but don’t know where I can go far with that.. what do you do?
