Can't seem to get a job, probably due to how anxious I get when I really want something. Any advice?

Hey guys, sorry if I am doing this wrong.

I just found this subreddit today and I thought that maybe I could reach out here for some help or insight on what I am doing wrong.

I am a 19 year old female about to complete her first year at uni. My major is computer science, but I've been programming for a few years now and have even been in national level competitions for programming. I have several certifications and I am really confident in my abilities.

I think my worst enemy might be me. I am a really strong scholar and I work really hard to learn new things. I just really suck at talking about myself. Upon being questioned about things about me or things I think I do good on I freeze up and I feel like it's visible.

I was really close to getting my first internship this summer (I was one of the very first people they called interview for an in-person interview). I was excited and anxious and it was very obvious that I was having trouble remembering to breath and choking on my words. Long story short, I didn't get the interview.

But that was the lucky case. Often times, I'll send out resumes and never hear back. It is a really soul sucking process and it has gotten me on edge (mind you I have been mainly applying for places such as home Depot and bed bath and beyond). Summer break is a week away and I have spent my every free minute flinging out resumes and emails, trying desperately to get a job.

Is there any advice anyone can offer? I think it's me and my anxiety but I don't know what to do? Is it possible I'm presenting myself wrong?

Sorry this was so long.

Tldr; can't get hired, probably due to anxiety. Any tips?
