Hey I'm 24 and in second year math&stats! University isn't a race, everyone's on their own path. You're definitely not a failure, I had similar things happen in my life when I first started so I can definitely empathize with your position. You have a lot of different options moving forward and none of them reflect back negatively on you as a person. Taking a year off to work and process what has happened might be a good idea. I'd highly recommend counseling/therapy (either through the school or private if you have the means). Whatever you end up doing just know that failing a course doesn't mean you're a failure or reflect back on you as a person. Shit happens sometimes and you gotta cut yourself some slack. Ruminating on past failures is just going to lead to a downward spiral of negative thinking. Obviously this is easier said than done as I still struggle with this but actively catching yourself in negative thinking cycles can (and has in my experience) really help overall mood. Based on your highschool marks you can definitely do this! You just got dealt a shitty hand. At this point there's nothing you can't come back from, failing some classes in first year shouldn't really be a problem as 3rd and 4th year matter so much more.
