I was on SSRI’s for about 2 years, no mania occurred since I was on a low dose, I went up to 150mg, then 200mg. And then everything went to shit. Mixed episodes, raging anger and depression. It led me into rapid cycling, was in mild psychosis due to mania and marijuana. 
I’m on Lamictal and Olanzapine at the moment. It’s helped greatly for the mania. But I’m still depressed, I used to be unable to get out of bed type of depressed but since going on Lamictal I’m able to be functional, but I still seem just as mentally depressed. I’m on 200 mg of Lamictal. I recently have gone through a lot of shit, have PTSD from December last year that keeps flaring up. Is it possible outside factors in your life can put your meds off balance? Because they were working quite well, then all of a sudden just stopped. I still get episodes, but they’re mild for the most part. Almost like a ‘watered down’ version of bipolar. 
Anyone know wtf is going on? At this point I feel like I’m gaslighting myself into thinking I’m not even bipolar
