New student at 30 y/o

Hey everyone! I really don’t have anyone in my family to ask for guidance in this and I’m starting to search to see what the process would be like for me. I have a GED and want to go to school. I want to go for rad tech which I know and have heard is competitive but I’m willing to bust my ass off to make it happen. The last decade I’ve pretty much spent helping out my sick family. I have some freedom now and want to pursue a career. Always loved the idea of medicine so this is something I wanna lean into. Any guidance or input would be appreciated hope yall have a lovely April.
