Hey there Jenn1fer!
CONGRATS on the good work!! You've made it this far, had good grades, so why can't you score a job?
Do you at least have a small job? That's a great place to start.
Have you talked with other social workers with experience before? I'm sure they'll be a great help.
Believe in yourself, just do it. There's nothing to worry about! Don't doubt a single thing, you'll do really well, and the reason why I'm saying this is because of your 3.0 gpa! That's something to be proud of, and it'll take you far.

A smile & positive attitude is what you need. Good luck!
