Am I wrong to feel this way?

My work friend is having a baby shower and I’m buying her all these things and I’m not mad she’s having a baby, I’m thrilled and I can’t wait to see her. But buying all these things just makes me wonder what my baby would look like in these things and why it can’t happen to me. I know it’ll happen one day but idk. It’s like a bittersweet thing. I can’t wait to see her baby in this though ❤️
