Hey- not 100% sure about restarting lamictal after a rash. I feel like I remember my old pdoc had said most rashes aren't the death rash (Stevens johnsons) but that drs sometimes are over careful.
Anyway, I have had experiences of condescending psychiatrists who do not seem to like their patients to be informed and ask questions or have an opinion that differs from their own. My first pdoc was a jerk who kept naysaying every time i questioned or contradicted him. I got really sick after weaning off Effexor (days of puking, headaches, chills, etc) and called him saying I had read ppl can have a hard time coming off of it and he said in no Uncertain terms that stopping Effexor at the dose he did would NOT cause any withdrawal symptoms! Like i was making up the physical symptoms i was experiencing.

A different pdoc seemed to encourage or at least respect my curiousity and well readedness on mental health stuff. I would ask him qs from something I read and he would politely discuss it with me, and not treat me like I was an idiot. My current pdoc unfortuately is not like that. I think some doctors feel threatened or maybe are used to treating patients who are unable to advocate for themselves. But I'm not stupid- I have a science undergrad degree, a masters, and almost went to vetinerary school. So yeah, I sympathize with practitioners assuming that we are idiots who are getting our online information from answers.com or Wikipedia or something. Sigh. My

If you really want to retry lamictal, I would suggest you find and print research backing your argument up, from reputable and recent research studies in academic journals and primary sources. Or else, get a second opinion. But just because somebody has a medical degree does not always mean they are right. Good luck.
