Feeling guilty

Im a sophomore in college and sex is new to me and I had sex with a freshman who ended up giving me a yeast infection and Chlamydia. He blocked me right after I told him and I just feel absolutely stupid for even doing the deed with him. Definitely feeling embarrassed having this infection because I haven’t even slept with many people. Not sure how to shake this guilt, I know it’s a lesson learned but it just wasn’t my brightest moment. Anyone have advice or a story like mine? I’d appreciate the comfort!

PS. I’m mad at myself but more so mad that this immature boy doesn’t care that he has it! I doubt he will go get tested because he’s in denial and he will keep spreading it to other girls! It’s sickening
