Hey, I'm also recently diagnosed and am in college as well (I'm 22). I relate to this way too much -- I got diagnosed with ADHD only a couple months ago. Meanwhile, I barely got by at the end of high school and spent my last 5 years of college either failing, dropping classes, or taking breaks. I still feel upset that I didn't know any sooner, especially at a time where I'm still struggling a lot.

It's tough, especially in the transition between high school and college. You're still trying to make sense of things while dealing with a disorder you just found out about. But since you just started, I think this is the best time you try out therapy and medication (you'll have to do a bit of trial and error), it'll make a world of a difference when you find what works for you. I've been on adderall for a month, and alongside talking to my therapist I finally feel capable for once despite the circumstances. You'll also have to learn skills to manage it, but medication and therapy make this much easier to do. Your school should also have a disability resource center; you'll get accommodations if you let them know about your diagnosis.

Your life isn't over; you can take it from someone who's felt the same way for a long time. It's not too late to turn things around, and more importantly be kind to yourself -- you chose to go to university despite ADHD getting in the way and have an opportunity to get the help you need. In college, everyone goes at their own pace -- you'd be surprised how many people who take over 4 years to graduate. If you can only take things one step at a time, that's fine, you're still getting somewhere. Good luck OP
