Having a denture, no matter its size, is always more about the emotional aspect. It speaks of the passage of time and all that implies - loss of youth and vigour etc. Once you accept that many of us require a little something to compensate for the years passing whether its hair colour, stronger glasses, a replacement hip or false teeth then you can begin to accept it. (However, I'll admit that the loss of teeth does seem the worst!)
I think there is almost a sense of loss and a mourning for what has gone that needs to be taken on board. It will pass and wearing a denture will just become part of you and your life.
As to the practicalities I'd just say buy the best you can afford as you need to trust it and the way it fits. Take it out at night ( I even leave mine out on the odd day I know I'm not going to see anyone (expect nearest and dearest). Keep it scrupulously clean and ensure you have the best mouth hygiene you can achieve - soon as you are wearing a denture it can lead to problems with adjacent teeth and gums. Once you take that on board and get used to the little so and so you will learn to ignore and even forget it. All the best....YOU ARE NOT ALONE.
