I am so afraid of making a mistake

I’m 71 and this will probably be my last home (SUCH a scary thought). I’m just venting, really, I know all I can do is as much due diligence as possible and hope for the best. I know no place will be perfect. Can’t help thinking: what if I don’t like it there? What if people there don’t get me/don’t like me? What if… Ya know?
