Any PAST/PRESENT depression/anxiety people experience this?

I have suffered from GAD/Panic Attacks for the past 6 years and only recently started taking meds for it. The meds have helped a lot in decreasing my panic attacks greatly. But lately i feel like i'm changing. I don't feel like my old self, not in a bad way necessarily, just different. I don't pay attention to details as much as i used to, and i see the world kind of in a different view. Is this because my mind is acting "normal" and i'm starting to think "right" again? Also, i feel like i'm forgetful more often, more like i don't care about remembering. When i was deep in my disorder, if i couldn't remember every detail about the day before, then i freaked out. Now, i really don't care about what happened yesterday, i just kinda brush it off.... and everything seems brighter, like i never noticed before, color is more vibrant, and i'm suddenly astounded by nature and existence in whole... should i worry about this, or is this normal?
