I don’t know what to do with my life😭😭

So I’m 29 years old. I have a son who is 6 by a previous marriage. My bf is 34 and he’s a police officer. We live together basically our entire relationship and we’ve been together almost 4 years in a couple months. He’s has a career but also does online classes. I have worked at vet clinics since I was 19 so around 10 years. Well now I clean houses. I actually make really good money to be honest and I have a schedule that’s flexible and works around my sons school schedule. But I hate my job. I would love to go to school and have a career like everyone else my age. But I don’t have a particular desire on what career path I should choose. Like a lot of girls we know are nurses, teachers etc. I want to do something important but aren’t interested in being a nurse or a teacher. I feel like my time is running short. Like soon I’ll be too old to go to school and no one is going to want to hire an inexperienced ____, that’s in their mid 30’s. Yes I could stick with working with animals but I got tired of working at vet clinics. They are underpaid, and their schedules are NEVER flexible. That is the kind of job that will work you to the bone with no home/personal life. I don’t know, I just want to do something different. I don’t want to be cleaning houses forever. I talked to my bf about this bc I get depressed just thinking about it and he’s says one day I will figure it out and I will get there. But what if I don’t? Are there any other ladies who have possibly been in my shoes before? Maybe some advice? Please no hateful comments. I honestly get really down about this and it makes me think what is my purpose in life😩😩
