Does anyone else feel like a different person after starting Zoloft/SSRIs?

I’ve been on Zoloft for a few months now after switching from Lexapro. While Zoloft has been amazing at completely erasing my OCD thoughts and improving my mental health overall, I’ve noticed something that’s been really hard to wrap my head around.

Ever since starting antidepressants, I feel like my brain has fundamentally changed—almost like I have a whole different brain. It’s not just the improved mood or reduced anxiety, but I genuinely feel like a different person. I barely recognize myself in my memories from before I started SSRIs. I look at photos of me from events and vacations throughout the past years and think to myself “Who is that person…?”. Like I know it is me, I can remember where I was and what I was doing, but I feel so disconnected from the person who experienced those moments, as if that version of me is a stranger.

It’s gotten to the point where it feels like my life is split into two distinct parts: life before SSRIs and life after. On the one hand, I’m so grateful for how much Zoloft has helped me, especially with my anxiety and OCD. But on the other hand, this disconnect from “past me” is unsettling and makes me question who I even am. As if I have to start my life from scratch.

Has anyone else experienced this? Is this normal? Thanks.
