This weeks new anxiety is gas leak. My usual is carbon monoxide. My brain  is going through hell right now making up these symptoms I can’t tell if they’re real or not. We live in an apartment that has a gas fireplace for a heater, since it’s hot out only the pilot light is on. I swear I keep smelling a faint amount of gas coming from the fire place. It’s really really subtle and I just get faint whiffs of it once in a while throughout the day next to the fireplace. I’m doing research and it says a gas leak is a sulfur smell, but I don’t know if I know what the smells like. To me it smells like a cast iron pan on a gas stove more of a metallic smell. I’m really freaking out and my fiance is getting frustrated with me because he thinks nothing is wrong and I keep bringing it up. I keep having panic attacks and going outside to breathe the air. I keep reading you’ll for sure be able to smell if theres a gas leak but my mind is playing tricks on me and I don’t know if the metallic smell is a sulfur smell and it’s super faint. I know calling the gas company is the only way to get a for sure answer but I feel like i’m just feeding into anxiety by doing that and will find the next thing to fixate on plus I’m embarrassed to waste someone’s time. My fiance seems annoyed by me wanting to call the gas company, he says ge can only smell if when he gets super close to the fireplace. Idk what to do :(. I can’t tell if me having a headache and getting dizzy spells is from extreme anxiety or from some sort of gas leak. Maybe this is all completely normal and I shouldn’t be worried, if there a was a leak the smell would have gotten much more intense by now.
