You could also be going through your period, lol. I get an emotional breakdown every few weeks that lasts for a couple days or so. Hang tight and see how things go next week!
Aside from that though, our daughter is only 6 weeks old now, and we're trying to go with mamma and babba (pronounced bah-bah) instead of dad, dadda, or daddy. So I suppose eventually I might be called bob or bobby (like mom or mommy), but either way, lol. I hope to get to where we're called Mommy-J and Mommy-K for our first initials. I understand where your wife is coming from though. Mine was adamant about her being mom, mommy, mamma, etc... It was like I was trying to usurp her title from her. Not that I was trying to diminish her in any way, but calling me dad, daddy, or father just seems like the wrong way to go since we can direct this from the beginning with her. We're working through it.
I wish the best for you. I heard somewhere that a lot of times the transition becomes what we live for, and when that's complete, there can be a big hole in our lives to fill. Don't let that happen, find some hobbies and distractions if you don't have any.
I get the piling on thing too! It seems like whenever life is going good for me, something comes along to knock me back down. The past 2 months have been medical bills. Baby delivery of course, but I've had tons and tons of doctor appointments at a $50 copay each because they're specialists. Plus treatments and deductibles and misfilings with my insurance, it's really getting out of hand. (Short story: I have MS and have had basically 3 relapses in the last 2 months. This week? I'm going blind in the left eye, yay! LOL)
Hang tight, we'll get through this. 🙂
