Because I'm (Un)Happy

It's almost 5am and my mind is restless. I worked till 12:45am today. I drove home, listened to music, and couldn't wait to just lay down. But now that I'm in bed, I just can't sleep.
A coworker and I went out for lunch together today. His name is Gurmeet. He's probably my favorite coworker. We take jabs at each other all day at work but we really do care about each other. Last time we went out to lunch he opened up to me about how he was bullied as a kid and his early childhood. This time we got on the topic of school and told him my situation. He was in a similar position a couple years ago with his parents. They wanted him to be a doctor but he just wasn't into pre-med. He tried to make it work but he actually started to think suicidal thoughts. That's when he had to sit his parents down and tell them he couldn't do it. His dad told him how disappointed he was. But now Gurmeet is so happy. He has a perfect GPA and is studying what he loves. He told me he actually feels happy and excited in his classes. I haven't felt like that in a couple of years. I loved psych. I took a psych class last semester but it was a repeat of a class I had already taken so I didn't learn anything new. I was always so happy and looked forward to learning. Gurmeet told me that it might really suck and it'll probably hurt, but I have to just talk to my parents and explain to them that nursing just isn't for me. Gurmeet wasted about $45k on tuition for pre-med over the course of a year. So while I may have wasted more time, he wasted more money. The hour flew by and I to go back to work, and he had to head home. He made me promise that I'd talk to my parents before Christmas. I know I have to, but it's so terrifying. My mind keeps going over possible reactions and outcomes and it's hard to get it out of my brain so I can sleep. Gurmeet told me that once he told his parents about how he felt, the weight of the world was lifted from his shoulders and he felt so much better. It hasn't even been a full week since I've decided for sure what I'm doing and it's killing me. I know they'll be disappointed but I can't push myself this hard over one class. Today I got affirmation from yet another person that I needed to do what was best for me and I'm making the right choice. I really am thankful to have a friend like Gurmeet. We keep each other sane at work and grounded out in real life. There are only a select few in this world who I open up to, and it's nice to know they all have my back.
