Struggling tonight... could use some support

My wife and I are struggling with our first son. Overall, he is a good baby. 11 weeks old, had been relatively happy, and had slept great overnight. I'm talking 6-9 hours for a few weeks. But that might be our downfall, cause the past few nights, it's been impossible. We knew it was too good to be true, but still. I'm sitting here in our first room next to the nursery cause my wife goes back to work tomorrow and she needs her sleep. I'm just expecting a sleepless night and being in the nursery a hundred times.

I keep trying to stay positive, but we're feeling the stress again, similar to when we first brought him home. I keep trying to think into the future with the milestones we're gonna hit. It sorta helps, but our hearts hurt from the anxiety and stress we're going through. My wife is in better spirits than I am, thankfully.

I guess I'm just looking for some solidarity and encouragement. Everyone (especially other dad's) say that it gets better and a lot more fun and I'm just jealous cause I want that so bad. I guess I just hate being stuck in the awkward pre 3 month phase. I envy the dad's who are having fun. I need patience, but I feel like I'm stuck in this newborn phase forever.

TL;DR: Help, encouragement and solidarity requested for a FTD with an 11 week old that is going through a rough patch. Sleep regression, mainly...

Edit: Thank you to everyone! I appreciate the encouragement. Trying to take this 1 moment at a time and look forward to good times to come 🤘
