When is it normal to get an internship for computer science?

I’m a Computer Science major at UCD. I’m a second year.
My GPA is currently a 2.85 which I know isn’t good, I had a pretty rough start in school due to anxiety issues but I’ve been doing pretty well recently.
This summer, I plan to get a couple of major requirements out of the way during the first summer session and I want to find something to do my second session.
I’m just incredibly overwhelmed and I don’t know where to start looking or what I should do, can I have some advice?
Thanks!

I’m a re-entry student. I would want you to check out Student learning disability center and get accommodation for test anxiety.
