How do I stop feeling so rejected?

There’s this internship that I recently applied for. I feel like this one is specifically for me because there was one I applied for a few weeks ago and didn’t get. This one is more in my range because it is for fashion and beauty which is the exact type of industry I would like to work in after college.
I want to be a journalist for a lifestyle or fashion and beauty magazine and this internship o applied for reached out to me. I was ecstatic because they are kind of known and have over 33 thousand followers on their Instagram. I’m so happy they were interested in me and they don’t pay but I know this will be a huge step for my career.
This internship is exactly what I need. I’ve had some writing experience before and they know this stand I’ve been told I’m a good writer. One of the things they asked me after reaching out was to pick an article topic that they have selected and then write an article about it and send them 5 potential topic ideas so that they can see where my creativity is.

In the message they said if I was selected for an interview, I would hear back within 5 business days and if I wasn’t selected then I wouldn’t hear anything back at all. I know my article was great and I had a few people read it. I looked on their website to kind of get an idea about their content and how they write and I think my writings were just as great and matched the content. I sent my article in on mid Monday afternoon and it’s now Saturday and I haven’t heard anything back. I’m kind of freaking out and feel discouraged and upset because it’s almost been 5 business days. I tried really hard on my article and did all the requirements. I’m feeling rejected and I know that my work was just as good. What should I do? Should I still hold out hope to hear something?
