I agree with you about these boards. One thing that helps, at least for me, is to open a separate window when you're responding to a long post (I'm doing that now with yours).  
 
First, I really sympathize with you. Ultram is one of those "borderline" narcotics that for some reason took a long time to be identified as addictive.  
 
Second, I completely understand your fear of withdrawal, but trust me...if it's medically supervised, it isn't that bad. I've been through rehab twice and both times the withdrawal was relatively easy, since the pros know how to calibrate your symptoms. And, In my case, it was alcohol, which is even harder than many narcotics to withdraw from. 
 
Here's the sentence of yours that struck me: "However, this med gave me a euphoria and instant good mood and it worked for the pain."  
 
Like many narcotics addicts, you "got started" because of a pain issue. However, at some point, that became secondary to the high you were seeking. This is a really critical point, because in so many cases I've seen (including my best buddy from rehab, who was addicted to vicodin), there's too much fixation on the pain aspect and that sets up an unrealistic expectation that you're not like "other addicts" since you first took the drugs for pain. It doesn't work that way, because your body doesn't pay attention to what got you started :) 
 
And this means that everything that applies to addicts and alcoholics applies to you, too. You will more than likely need a medically supervised withdrawal (ideally in a treatment center) and then you'll need support (ideally AA/NA). You may think this sounds nuts, but it really isn't... 
 
For starters, do you have insurance to cover any kind of treatment?
