First generation college student

Okay so I recently graduated highschool in 2017. My parents are from Mexico and never stepped foot into college. I’m the oldest out of my siblings. The last month of my senior year I sent my application to TCC . I went up to TCC in August to register and they told me I couldn’t go there because I put that I’ve attended these so and so universities on my application , and my dumbass thought the question has asked me what universities you want to attended. I rushed through my application and i regret. So the lady told me to email those universities and have them write a letter of Un-attendance then come back to her. So I did and some of the universities had a bunch of emails and some I couldn’t find it and well it’s just an annoying thing I have to fix before I can register. It’s been a year already. I’m slacking I know. But I’ve emailed some and they haven’t written back. My mom is giving me shit saying that I’m a failure that I’m not gonna do nothing in life if I don’t go like as if i don’t wanna go, which I do. It’s just gonna take me some time. And I’m currently un employed too and I’ve been applying to jobs but none have called back so basically I feel like I failed my mom and my self. I feel unaccomplished.
