Step one, accept. This one you really have no choice in. Once you accept, everything becomes easier. Not necessarily easy, just easier.
With the knowledge of the situation in mind, adapt. Take this new knowledge with you as you go forward. Use it to your advantage.
Embrace your new reality, embrace your new potential. Realise that your experience to date comes with it unique insight that once embraced, empowers you.
Accept. Adapt. Embrace. Empower.
