I can only share what I know, which is doing it.
I felt stuck, like I rushed through the game (not TTing, I mean more like every day I wanted to just decorate everything, measure everything, make everything perfect). So just entering the game was... stressing me out, putting me in a bad mood.
A friend held for me Sherb, since he had a free spot and while some offered I didn't really want to force my friends to make free spots just for my mistakes. They asto held by bells and some items.
I love it. I'm in love with my new island that I've decided to take my time with. I did put the release date, to slowly come back to the present day (jumped egg hunt because I'm not going through that again, I still dream about eggs everywhere). Problems? Mostly DIY related, lost my dreamie Fang, which I had fell in love with in this game (hadn't met him before), but I'm sure I'll have him sooner or later back ^^
Maybe you can find someone that could hold your dreamies?
In the end whatever you do, try to now pin point what is making you sad/mad/uncomfortable about your town. Is it because you went full in with the decoration part? Is it the mouth rivers? Is it the town hall placement? I think those kind of small details could be the key for you to be happier with your new town, or if you don't reset, maybe to realize what is failing
