Thanks CodeGeek for pointing out the perspective. Before I read your comment I was recalling my bad day.
holdonthere, I tell you, it will not be nice to go fly to foreign country and look for someone so broken and miserable (if you ever plan to do it). I know it because I did it before. I had a friend who was sick and suicidal in a way and she was in a foreign country, away from home and alone. I decided to go over there to chill her out, even though I did not know where she really was or her latest residential address. I could somehow meet with her, (I had her email address) but it did not end romantically. I thought I saved her life but she said I was nothing but bothersome to her. I admit I was selfish and I dreamed about being a hero or something. It still pains me a lot. For suggestion, maybe Facebook will help, somehow? You know in Japan you can find your wallet you have lost in subway. So why not a human being?
After all, it is up to you how or what you are going to do with it. But hey keep your head up mate. Surprised to know US gov. publishes the detective services in Japan on their website.
By the way, I thought you wrote your message in English, Japanese, and Spanish at the first glance. But realised you wrote Japanese words in Alphabet. That is neat but makes me wonder what I was reading...
