stain mark

I am really stressed out over this stain mark on my hardwood floor. Last weekend, I spilled some red wine during dinner with friends, and even tho I tried to clean it immediately, there's this awful stain mark that just won’t budge! I’ve used everything I could find, from vinegar solutions to commercial cleaners, but this stain mark just laughs in my face. Every time I walk by, I can't help but feel frustrated. I did a bit of research and found some tips but I guess I'm just not sure what to believe. Is there a special method or product that can actually get rid of a stain mark like this? I heard some people say that some stain marks can permanently damage the wood, and now I’m super worried that my floor will never look the same again. What do you guys do when facing a stubborn stain mark? Is there a chance it can come off without needing to sand the whole floor or is that the only way out? Any advice would seriously help me because this stain mark is driving me crazy! Thanks in advance!
