feels like i've wasted my time somehow

i'm graduating in 4 semesters with a degree in information systems and it just sort of hit me that i've wasted my time. i wanted to do English +Education Minor and TESL but my parents threatened to kick me out if i did not do something "useful."

I just had a weird sort of awakening. I started crying suddenly. I lurk in TEFL subreddits and around spaced dedicated to the countries I wanted to teach in and they make ridiculously good money. It's not really about the money to me though. I just feel like I've wasted my time. I'm on here on two scholarships and it's just... I could have graduated by now with and been doing something I genuinely cared about. I just feel so numb right now. I need an internship to graduate and I havent bothered started looking because I know that I'll just hate it.

My paarents have grown tired of me living with them (even though they are the ones who moved with me to college w/out me asking) and they want me to get a job. I pay rent and groceries and bills using my scholarship money. For the most part I just stay alone in my room. I don't have friends. My grades are average. I'm looking into grad TEFL/ linguistics programs but I'm scared I ''m just gonna fail at that too because I have a bit of a speech impediment (I used to go to speech therapy but my parents pulled me out of it when I was 14 :/)

Sometimes i just want to drop out and become a commercial diver or something
