Has this happened to anyone else?

I’ve been on 40mg for almost 2 months for anxiety. I have been feeling amazing, but the past day or so I have felt an unexplainable sadness. I don’t normally struggle with depression, but I imagine this is what it feels like. I can’t think of anything in my life that might be causing this feeling. Has anyone had a similar experience? Is this something I should tell my psychiatrist as soon as possible?

Please feel free to tell me if I am being a drama queen
