Hi everyone. This is my first time posting, and I am also using mobile so please excuse and format errors. 

I (19f)was diagnosed with bipolar disorder about 3/4 months ago after going back to therapy and a psychiatrist. I’ve been struggling with mental health issues all my life and it was always labeled as depression and anxiety. 
They started me on a mood stabilizer. (lamotrigine) They slowly upped my dosage to 150mg. (this is the second one my physiatrist put me on. I took 1 for about a week and it made me severely sedated and I was constantly disassociating)

I though maybe the meds were working at first, but I didn’t feel a drastic change. But I woke up about 5 days ago and the inside of my head felt completely different. At first I though it could just be a number of my usual symptoms/behaviors, but I’ve slowly settled into this feeling and I’m not sure how to describe it. For the first time in my life I feel like my brain is quiet. Not in the way that I disassociate, but that there’s not as much noise in my brain. (ex: the constant overthinking, inability to focus, making up scenarios) 

It was scaring me the first couple day. I hate change, and feeling this difference was hard to explain to myself. 
I told my boyfriend everything after a few days and asked him if I was acting differently. He told me that I was okay and acting as I always do. We talked about what i was experiencing, I cried, but it made me feel better. 
I don’t feel sedated, separated from myself or reality, but this clarity is such a new and daunting experience. I’m realizing how much noise has been in my head my entire life. 

Sorry for rambling, I just wanted to give a full perspective. 

but basically what I’m asking is, is this new sense of clarity normal, could this be a new intense manic episode, is this a normal reaction to new medication??? I know I need to talk to a professional, I have a psychiatry appointment next week. but I just really need some advice or a better understanding of this experience from somebody who has gone through it or is going through it. Thankyou
