will I ever find a job?

I am majoring in environmental engineering, graduating next spring, have a low GPA and can't seem to find an internship even though I've applied to several places I only got two interviews but they both turned me down. I work really hard in school but seem to always have test anxiety and do bad even though I know the material. I have been involved with engineers without borders, a hall association, did undergraduate research through a professor for a semester, participated in an environmental ethics mentoring program, and am currently volunteering at riparian preserve for dragon fly surveying. I am extremely frustrated because I don't want my degree to go to waste. My friend who is a film major who parties all the time and thinks he can magicly get into Hollywood who somehow landed an internship has a better shot than me. Anyone feel this way?
