Please read my post when you get time. You are not nuts or loosing it. You are on Singulair. I had almost the exact same symptoms along with 28 pages of postings from people on this site. I was thinking the same things. Do I have a tumor, what is my problem, where is the old me. I have been off Singulair for 4 days and allready feel better. My mind slowed down from 100mph all the time. Much happier as well. Others say it may take two weeks to two months to feel 100% like your old self. Good luck and get off this crap.
