Mania can be dangerous to your relationships and financial situation if nothing else. Lamictal is not considered to be a strong counteraction against mania. SSRI's can trigger mania and certainly never help control it. If you really want to control your mania then you'll have to keep trying effective drugs until you find one that works and which you can tolerate. People who are well-controlled for mania (which you apparently are not) can often deal safely with an antidepressant.
