Anyone feel like they are going to miss their old life without kids?

I feel really selfish for thinking like this. I’ve always wanted children so I’m surprised I feel this way.

I feel like I’m going to miss my old life, feel like all my relationships are going to change. I am so close with my parents and I somehow feel like that will change once the baby is here? Even down to my pets and feeling like I won’t have as much time for them and dealing with guilt there too.

I just feel really apprehensive for the baby to come and how it will change everything. It’s getting me down terribly.
