Change is causing anxiety

My neighbour 2 doors down has just put her house up for sale and this is causing me to feel unsettled. I'm anxious about who will move in, what will they be like, will they be noisy. I know everyone wonders this when they get new neighbours but it's causing me to become anxious and interfering in my life. Also the path outside my house has been dug up for city fibre and the new line on tarmac all the way down the path is different to how our path normally looks which makes me feel a little strange. I think because it looks different I dont know. I always get very anxious when things around me change
