Smell Sensory Issues?

TW: emetophobia

Is anyone like me? My biggest sensory problem smell but with certain things. Let me explain:

First of all, I got diagnosed a year ago and I have not always been this way but I like things that smell objectively good (perfume, candles, etc.) but things that smell bad (garbage, dirty dishes, old food) are so hard for me I will physically gag, dry heave, or get sick.

Because I am not full blown sensitive to all smell I can’t tell if this is my adhd or a symptom of my chronic acid reflux. Anyone else in the same boat?
