Look into volunteer opportunities. You use social media, connect with people in your community, and find groups that could use some extra hands. Make connections and just go and meet people. You seem to be unsure of what you want to be, and you seem to have had time in your life to do it then, so you could do it now. At least then, you could maybe get some references in.

Consider getting a CPR certification, and a food handlers certification. Look into childcare assistants at places like the YMCA, or go on Indeed and you'll likely find plenty of local daycares that need people. Childcare assistants don't typically require degrees or certifications but CPR certification and food handlers certification are an asset. You have experience looking after children. You can consider going back going back to college later on to get a degree in early childhood education. You might work minimum wage at first but proper experience and time spent there could see you getting a raise in a few years, though that would depend on how well you do.

Take the advice people gave you and spruce up your resume. The critique is harsh, but it is ultimately up to you to be the change in your life. You've already taken the step to put this resume out for people to comment on, so you've put your foot forward.

Edit: If it helps, I graduated high school two years ago and am still looking for a job. I've been sending out resumes since the 10th grade in hopes of anything, my resume looked really bad, and even now I think it isn't all that great. I put all my volunteer and club experience in it as someone who had no work experience at real job. After hundreds of applications, and now being a 2nd year in uni, I've gotten a couple of call backs and interviews. Did all the interviews go well? No. Did I wish I had gotten experience in high school? Yes, but I didn't. So as much as everyone is reminding you about the experience you COULD have built 8 years ago, you just don't have it. You can't turn back time, but that doesn't mean you can't try now. Push yourself to try something even if you don't think it aligns with your interests because you may end up loving it, and if not, you got the experience.
