I’m 18 years old, and have been struggling with depression, anxiety, and undiagnosed ADHD and/or autism for as long as I can remember. I’ve been taking sertraline for about ten years, but because it hasn’t been working as well as I want, my psychiatrist prescribed me lamotrigine a little over a month ago. I took 25mg the first two weeks, didn’t feel any effects. The day I bumped it up to 50, for one brief night I felt something I hadn’t felt in a long time. I was legitimately content with my life and felt like a child again, rather than someone going through a midlife crisis as I do now. I was excited to do things, I could read and do my homework just because I wanted to. The next day, however, I was back to my usual lethargic, cloudy-headed self. That was two weeks ago, and I have raised my dosage to 100mg three days ago. I still feel nothing. I had hoped it would start working by now, as I’m in my last quarter of senior year and don’t want to waste it being unable to do homework and having existentialist thoughts. I’m wondering when this medicine usually takes effect, how it feels when it takes effect, and if it can suddenly start working without raising the dosage on the same day. Is what I felt that one day two weeks ago how it feels when it’s working? I’m sick and tired of being depressed, unmotivated, and empty-headed, and I don’t know what I’d do if this medicine didn’t work.
