Junior with 2.8 gpa....am I screwed?

Hi! I am first semester junior at Penn State(Main Campus) and I am majoring in Mathematics and Economics. Currently my cumulative g.p.a is 2.8(I had a 1.56 first semester of freshman year) and my major g.p.a is 3.2(for Math). I have applied to many internship positions but I have not heard back from any of them. Most of the professors turn me down for research positions because of g.p.a. I don’t know what to do I am hopeless right now. Any advice or suggestions will be really helpful!

Thank you so much.
