Norepinephrine, serotonin and dopamine in relation to anxiety

So I've been struggling with progressively increasing anxiety for about four years now, I've been through all the first line treatments including SSRIs. The only drugs that has helped at all so far have been Buspar and Remeron, both of which eventually stopped working for me. I've been doing research and found that Buspar works on serotonin and dopamine while Remeron works on norepinephrine and serotonin. SSRIs (I've tried Zoloft, Viibryd and Lexapro) work primarily on serotonin had zero positive effect on me in anxiety or depression.

So I've been thinking about Wellbutrin, which regulates norepinephrine and dopamine, which I suspect is what benefited me in the two drugs that worked. Before I did my own research, I brought up Wellbutrin a year back in which my psych doc dismissed it because it may exacerbate anxiety. However I think it may now be worth a shot. Is my logic sound here, and should I mention all this to my psych doc? Or am I way out my league with the research I've been doing?
