How do I learn to embrace change and start over???

It's more a case of deciding to accept the changes, until they are no longer a daunting prospect. You will be surprised at how fast you adapt.

Be Proactive not reactive

Take it one day at a time. Don’t get overwhelmed.

set goals, Baby steps, get support if available

By realizing and accepting there's no other choice unless you want to move forward and be happy.
