I 25M learned that my crush 23F is interested in someone else. Should I reveal my feelings?

I’ve had a crush on her for almost 2 years. Unfortunately, I never had the balls to tell her anything. At work she’s the closest to me and vice versa. I felt like it would’ve been a bad idea to mix romance and work. Regardless of how well we meshed.
A couple days ago we had a party amongst close friends. She had a bit to drink. Revealed to some of our friends her crush who is another coworker. My homie being my homie told me. I felt a lot of heart ache.
None of this is on her by the way. I do not blame her for liking who she wants to like. She isn’t obligated nor should feel responsible for how I feel.
One of my best qualities is my perceptiveness. I tend to analyze people and small things they do. So I always had an idea that she might of liked my coworker. I was never able to tell if she had any sort of interest for me, but I always leaned with no, because I didn’t want to get my hopes high.
I don’t know whether to follow my heart or brain right now.
My heart wants to tell her how I feel about her, my brain wants to keep it to myself and just move on quietly. I want to avoid the awkwardness, because it’s unnecessary she is not will not be interested. On the other hand I feel restless holding in this stupid secret, and want to be rid of it.
