I think the experience I had with Lexapro/Lamictal/akathisia and the experiences I have with PMDD could be kind of like a mood of anger/irritability. It's like getting stuck in that state for a prolonged period and it's way more intense than I would normally feel about a situation. With the med situation I felt like trashing my room and did punch some things which was uncharacteristic. I would exercise intensely to try to get rid of it and isolate myself. It was hard to see past it. My psychiatrist asked if I felt more impulsive on the medication and I said I didn't know even though I for sure did, because I just had poor insight. I don't know what's causing it for you, but I relate to what you describe. I hope your mental health professionals can get you feeling better, whatever the cause.
