I-copy/pasted my whole PhD dissertation. My compete University Career was a lie

I'm 34. Australian. I-copy/pasted my PhD dissertation. I'm an IT Project Manager for a federal Government Agency working on National priorities projects. I'm choking. I can't cope. I can't look at myself in the mirror. I feel sick. I feel so overwhelmed. I feel defeated. I hate myself. My-copy and paste PhD dissertation passed and I recently graduated. I felt like celebrating but didn't know how. I'm ashamed to celebrate something that I didn't do. I cheated. My whole University career was a lie. My three university degrees are a lie. I'm no academic. I didn't know what I was doing. I never knew what I wanted to do. I was so empty, a void. I had no-one in my life who I could speak to about this. I'm ashamed. I'm sad. I cried. I'm crying while I write this. I feel like I was a failure. I'm a fake. I'm ashamed to reveal this. I'm so embarrassed.
