What do I do when I'm in love with someone I've no contact with

So I just came back from a holiday to Thailand with my friends a few days back. While we're there, everynight, for three nights, we went to this massage parlor and this same masswise massaged me every time we were there. We chatted quite a bit, laughed and bonded a little although she could hardly speak English. Now that I'm back, I realize that I keep thinking about her. I have fallen in lobe with her, deeply. I feel destressed, I don't have any contact with her, no pictures nothing. I feel like pulling my hair off because I miss her that much. She is just an ordinary girl that's killing me inside. Please tell me what to do. I don't know when is the next time I'll be going back to Thailand. And I don't dare to talk to any of my friends about this as they'll think I'm a freak. I need some help. I don't want to live love sick and without appetite to eat most of the time. Please tell me what to do. Thanks.
