Graduating without any internships. Any tips?

I am graduating this fall without any internships under my belt and I feel very distraught. I have been applying so much, working on interesting yet practical projects, and tailoring my resume to specific job descriptions and still nothing. I have had referrals from multiple people and still nothing. I know it is such a competitive field but i’m starting to feel burnt out, but this is all I have going for me. I don’t want to let anyone down.

Any tips that people could give who may have been in a similar situation?
