Hi Corey. What I would suggest is to call the doctor up tomorrow and discuss your doubts about the medications. I unfortunately am not familiar with those medications, but if he has been working with you this is the course of treatment he has decided for you.
From reading the Wiki's it sounds like this is a proper course of action, the Risperidone needs to be introduced into your system and in the meantime the Lamictal is used to help control mania and mood swings and once the Risperidone is in your system then the Lamictal is no longer needed.
I thought that I was Bi-Polar but now I know I have boarder-line personality disorder and I am sorry that I am not of more help since I don't have the same symptoms as you.
What you need to ask yourself are these questions
Do I trust my doctor with my care/well-being/medication?
Would you rather not take the medications because you are anxious that maybe they are not the right ones, or would you take a chance it will help you?
I can't tell you what to do, in the meantime think about good things, things that make you happy, read, watch a good movie, call up a friend, or anything that will take your mind off of this and call him first thing in the morning. In the meantime, if he did not give you a 24 hour hot line, call this number
