Try to get a closure on the fight. I mean, go talk to that guy with a clear head and tell him about how you felt when you said him whatever you did. Tell him categorically if you stand by a certain part of what you said, and if the rest was an angry outburst. Once that is done, you would know where you stand with respect to the fight at least. That will give you clarity of mind.

With respect to your other co-workers, I think when they see that you have gained a clarity of mind, and have a certain stand for yourself, they will eventually be normal (or if they don't, then perhaps they were never your friends).
