Adaptation doesn't happen overnight. It's a process. It takes an amputee awhile to come to terms emotionally with the idea of only having one leg. It takes them a bit to learn to use a prosthetic as well. There are stumbles and frustrations and errors are along the process - until the "right fit" is made for every piece of it.

How to cope mentally with the loss of the original leg
Healing the surgical wound to fit a prosthetic
Getting a prosthetic that is the correct style, shape, size, and has the features that allows for the most comfort.
Learning how to best manipulate the prosthetic for each task throughout the day so your day is easiest.

This is how an amputee adapts.

They may then even look into groups or activities designed specifically for amputees.

See... in some ways each of us are similar to an amputee. Only our "prosthetic" is not physical. It comes in the form of mental health care or alternative therapies. But our "loss" is equivalent - you just cannot see it as well because the brain is internal rather than external and our losses deal with differing parts of our brains. So - we must come to terms with the loss. Then be "fitted" with the right "prosthetic". (Aka: find the proper care that is best suited to you and your needs) Learn how to "manipulate the prosthetic to make our lives easier." (aka: use what we learn in our care to make our lives flow easier)

Then we may decide to join groups and activities designed specifically for people with our "losses".

Does that make sense?
