If I relied on the shidduch system, I would never have married my wife. You will have to work harder to put yourself out there, but it's worth it. Don't be shy about asking friends if they or their spouses have any ideas.
I wonder if it might help some people if stories like this were publicized more widely. Not necessarily your particular story, but some way to let those who are feeling unsuccessful in the shidduch system hear about those who found their bashert through alternative methods. Like an edited volume, with each chapter telling the story of another happily married couple who found each other without a typical shadchan - perhaps described first from the point of view of one spouse, then the other.
