You're in a healthy place ... but:

Depression doesn't seem like it's in your vocabulary right now, which is great. But beware of sneaky triggers, such as difficulties with a new or ending relationship, and symptoms like loss of (or change in) appetite, appearance, weight gain, even acne, wrinkles or other changes in your skin. "Any major life events, including 'positive ones,' can trigger depression, as can a 'minor' life event," said Los Angeles psychiatrist Dr. Bruce Spring.

Be sure to value social interaction and occasionally take time for yourself, whether it's giving yourself a spa day, trying a new workout class or burying your nose in a great book. If your days seem to get increasingly gray for some reason, or if you're going through any significant changes in life (a new job, a new relationship, a tough loss), consider seeing a therapist to talk your way through it.
