No problem! I think that it's pretty normal for patients with DID to go through a revolving door of lost doctors, unfortunately. The docs should just admit to having no experience treating it, but they don't and end up fumbling around...*sigh* I got very lucky and had a couple of amazing patients right away at the beginning of my clinical rotation that had DID. We got to work together for several years and navigate the broken system together, so I definitely feel your pain on this one. In the end those patients had to be their own best advocates because there are so few doctors out there that know how to treat it.
As for Risperidone, I like it in that it also serves as a mood stabilizer in small doses like the dose you're taking. As long as it isn't too harsh, it can be a good adjunct to a regular anti-depressant. Also, it doesn't have some of the side effects of some of the other mood stabilizers (depakote can cause hunger, and thus, weight gain). So, if it works for you, I recommend it. It can assist in sleep too, which is good.
In DID I think that there are several things to always keep in mind when medicating:
1) nothing that will enhance the dissociation (no benzos)
2) something to target the depression
3) something to stabilize mood
4) something to enable sleep if it's difficult (again, no drugs with potentially depersonalizing properties - for example, ambien and lunesta can increase dissociation).
All in all it sounds like you're on the right track and if you have any more questions, please don't hesitate to ask!
