I've been hiding my second gender for years, until my Alpha boss found out. What should I do?

My boss from Wells Company, the biggest company in the country, just found out that I'm an omega, what should I do?

Although the biggest company there is, Wells Company is notorious for discriminating or mistreating people whose secondary gender is Omega. I have been hiding and identifying as a Beta. I make sure to eat suppressant medicines, herbs, control my pheromones, and having a constant check up.

My boss, Director Kil Yooseb (길유셉), found out when I suddenly had a heat attack. It was so sudden that I couldn't bring myself to get back up and take my medicines. Director Park saw me helpless, which I am embarrased to be seen like this.

I was too weak by then, I couldn't control my body. My vision was becoming blurry. But I could see the director's face, seeming worried. At that he asked me if I could drink the medicine, and I didn't have a muscle to say "No." I also remember that before feeding my medicine, he said "I'm sorry.." then proceeded to feed me the medicine by his mouth.

My memory then became hazy, but I remember Director Park covering my face and carrying me. Last time I could remember was him putting me in his car. I am thankful that he was there, but I'm so anxious whether he'll fire me at my job because I hid something from him.

I am currently in the hospital trying to recover. My doctor said that the reason of my heat attack was because of constant taking of suppressant herbs and medicines. However, I am not worried about how did my heat attack occur, I'm more concerned on how I could face our Director knowing well that I lied on my resume and on his face.

Can anybody help me on my situation?
