I would bet money that your anger is a side-effect from increasing your meds.

When I was on Lamictal, my Pdoc increased it hoping it would help what I thought was fibromyalgia. At first I felt much better, but within a matter of a few weeks I started having this level of anxiety and almost panic to the point I was in tears over nothing, and afraid to close my eyes to go to sleep. Finally, I remembered my sister telling me that her daughter's neurologist had told her that these types of meds have anxiety as a side-effect. I googled it, and sure enough, it was listed as a side-effect. I went off it as it had also triggered a receding hairline, and within a few days, the anxiety and tears were gone. I wouldn't be at all surprised if you aren't experiencing something similar.
