I had an argument with a friend a week ago and still hurting

About a week or so ago, when it was my brother's birthday, I had decided to confide in my friend about my problems. Our friendship is weird, he lives in New Zealand and I live in the U.S. and our connection only formed when we had came across eachother on a site. We've known eachother for three years now, and I would be lying if I said there wasn't turmoil here and there. Our arguments, if we had one, would result in an absence of talking for a while, maybe one to two weeks at the most? Well, it's the second week since we've stopped talking and I can't help but feel this stabbing pain in my stomach every time I decide to think about the situation. The thoughts range from what I could have done differently to utter resentment for him and eventually it wanes to me feeling sad that I couldn't have tried harder to maintain my composure during our dispute. For a few days I thought I was able to at least not acknowledge it, but as I was talking to another friend we both know, I had the compulsion to ask questions regarding if they still talked and let me tell you, I regretted that immediately after. Of course they still talk! They chat a couple of times a day and here I am having to endure this silent treatment for my gross handling of my emotions and frustrations. Having talked to most of my friends they all tell me that time will the wounds but right now it's not about the end of the journey but more along the lines of me needing to withstand the anxiety and jealous that runs rampant every time I decide to think about him while we are not talking.

Paranoia runs through my mind regarding the situation and I just wish I could move on with my life without having to sulk over this. Even now I'm having to endure the stabbing pains of anxiety and it makes me want to curl up and sob my eyes out until I'm exhausted. The rational part of me wants to move on and wait until he's ready to talk again but the anxiety and emotional side of me is compelled to think over this until I can no longer stand it, like part of me is demanding a form of retaliation just for being ignored but I know that would make things worse.

Long story short, I'm miserable. My sleep schedule is ruined over this and any time I wake up I get the sharp pangs of dread that are ready to remind me that I am still having to endure this situation. If anyone has experienced the silent treatement and tips on how to cope with it, I would love to hear any suggestion because right now I'm at my wits end trying to deal with the anxiety.
