HAHAHA!
Ok, then I'm going to say "IT ABOUT TIME TOO"!
Its not a 'final leap', its just a step in the right direction.
You've spent too long on the fence and you've mentally built this whole thing into a much bigger deal than it needs to be.
I know, because I sort of did the same myself.
Thats about the only thing you should feel 'guilty' about.
If your front tooth fell out, would you feel guilty about replacing it?

By now you SHOULD know all there is to know about ordering, wearing etc.
This will help you, but be prepared that 'knowing' and 'doing' aren't the same.
With your curly hair type & colour I honestly think you'll get some really good results.

I think your struggle might be the mental side and you need to work at that as much as the practical stuff.
Each scenario will be a little challenge:
First time meeting up with friends, relatives.
Going to a social function
Bumping into someone you've not seen in ages
Even walking down the street for the first time.

I promise you, for each scenario, nothing bad will happen, no-one will be staring but its up to you to meet people with your head held high and truly notice the lack of reaction you'll get.
Don't go searching for subtle nuances that you can mentally turn around into negatives.
Thats all in your mind and you HAVE to be aware of that.

The most likely thing to happen is that you'll get compliments and you must learn to accept them in the genuine sense that they are given.

Think of the whole thing as an acting role. Its a part you're playing and you have to BECOME this confident character. To do that well, you have to get the 'look' right and get into the character mentally.
Putting on the hair and striking the right attitude is exactly the same and I know you can do it.
