Home renovations/remodel

[Tree City]

Have you ever had a major home reno or remodel? We are currently in the midst of a renovation and I'm at my wit's end lol. While I am both grateful I can do this and excited to eventually see the final result, I am also annoyed at delays and cost bonkers-ness (thanks, inflation!).
I've been waiting 4 months for an egress window permit. (My basement doesn't have a window big enough to allow emergency help to fit into my home / residents to escape. An egress is required to finish the basement, which I want to do so my out-of-state family can stay here when visiting and so my kids have a fun hangout for themselves and friends.) My contractor says they've never had these holdups before. I am not feeling good about that lol.
So, can anyone reassure me that everything will work out, or at least get finished? I know this isn't a real "problem," but I'm still stressing. And if you have Reno Woes, feel free to share! I know it's stressful to have work done to your home!
