I'm all for self-fulfillment and independence, but I think you're being a little hard on yourself. It was the day after you broke up with the guy--of course you were feeling sad and empty. There is such a thing as a grieving period, you know. What were you supposed to do, shrug and say "Oh well," then go to a fencing lesson?

Look, only you know how you felt, but I see no connection between feeling empty the day after a breakup and not having a full life. Nobody has a full life the day after a breakup, even if s/he initiated the split. You're in shock, and feeling sad, lonely, scared, guilty, empty. That's normal, and certainly not the time to assess the fullness of one's life. No one is thinking clearly the day after a breakup.

But if you still think your life needs some depth, great, go for it. It never hurts to meet new people and try new things. You can try volunteering, take some fun enrichment classes at night (writing, cooking, dance, etc.), join a club. There are hundreds of ways to put yourself out there. Find an activity calendar for your local area and see what's happening. It might take time, but I bet you'll find your passion soon enough.

In the meantime, cut yourself a little slack. You're human. I know I often preach about having a full life independently of a guy, but I don't mean you have to start doing it the day after you break up with someone.

Thanks for the question.
