applying product design

Hey everyone,
I am around 23 years old and thinking to return back to college and finish a degree of product design.
I am current working with a 3d printing company of tutorial department.
However, the department got cut and I going to be unemployed. So I’m thinking to do sth I like in a long time.
I apply to industrial design before, but i did not pass though the portfolio section.
I am not an artistic person. I dont have much sketchs. But I really enjoy with design product.
I also dont have a good sketch or presenting skill.
I dont know should I go apply to college.

please give me advise.
