Is it too late to go to another college ?

So basically I’m 22 , Im already in college finishing a degree but as of last year I decided what I’m studying isn’t what I want to do .

To simply put it Im in design school / art school the area where my school is and where I live are the best place in the country for those jobs. I do textile design and I double minor in international marketing and sustainability .

Anyways when I was younger I always wanted to be a vet or do something related to ecology or animals & the environment Ect . I love science and my sustainability minor required me to take science classes which I enjoyed 200x more . I feel passionate about it.

The reason why. I didn’t go to school to be a vet is bc i couldn’t afford it and my parents aren’t helping me the design school I choose was the lowest good quality school I found . So it was my plan b .

I graduate from my current school this May 2018 .

I was contemplating going to a local

Community college where they now offer a vet tech program which I know isn’t the same as being a vet or vet school but I was looking into it and I feel like I want to try it .

Do you guys think it’s a mistake or bad if I continue to go to college even after I graduate the one I’m currently in ?

To be quite honest my problem is that I feel like a failure and like I wasted money going

To school for something to only realize I don’t like doing it . And even more so a failure bc i wanna jump into another school .

What are your opinions ? Or advice ?

( btw i have the grades for vet school since high school I’ve kept a 4.0 gpa and in all Ap and honors courses and in college same 4.0 gpa . )
