I personally wouldn’t. A lot of people have felt the same way on this forum and have made threads about it asking as well. If you made a lot of progress and are still on the fence about restarting, then just give it a little more time.
Some things I’d suggest are either taking a break from ACNL for a bit (to kind of refresh your brain), go visit some DAs to see how others style their towns (this tends to give inspiration for your own town), or walk through your town a couple of times and imagine what you’d like to see/get rid of. One of these might help to keep you grounded.
But, if you STILL feel this urge to reset, then I think that might be for the best. Sometimes forcing yourself to rely on no one else and begin anew can re-kindle this attachment and inspiration for your town.
I wish you the best of luck no matter what you decide, adidas! (^ν^)
