Going from being highly regarded to a disappointment with your old friends and your family is a hard pill to swallow. It's a massive life-change and will leave a vacuum that seems to belie the wisdom of what you're doing. The psychological effect of going from a community where you're respected and accepted, into a world where you're just another fish in the sea, takes some getting used to. That's only natural . . . and it's not easy.
What Ding said . . .
As much as possible, try to focus on the present and on creating a better future.
. . . is good advice. It takes time and effort. But in the end, what you DO from here will define you . . . much more than what you will ever say.
