maybe need a revisit with my psych about things not working out?

I am recently diagnosed and I've been consistently on dexmethylphenidate (XR) for about 5-6 months now, and all of a sudden this past two weeks I feel like I might be having some of my old symptoms os overwhelmingness/anxiety/not able to do anything. I thought maybe it was my period week last week but it still continues and I notice myself eating more, and getting more coffee to sort of calm my brain. I finally made myself make an appt with my doctor to discuss this next week.

Has anyone experienced this? It feels like all the goodness that meds helped with this past 5 months just stopped and I feel like I don't want to be stuck like this.

I'm also trying to type this out mostly to help with my anxiety right now. I would appreciate any thoughts/ stories of your experiences. Thank you.
