I've been having a lot of anxiety lately about my bedroom, which is located very close to an attached garage. The door to the garage is less than 4 feet from my bedroom door (separated by a mudroom), the garage itself is less than 4 feet from my bedroom (separated by a small bathroom), and I can smell the general garage smell even in my room (which is essentially like a basement room with carpets. It and the garage are the main two rooms on the base floor of the townhouse I live in and are in very close proximity). There are two cars (mine and my roommate's) and a furnace in the garage, along with paint, a fuel tank and other misc items.

The past week, I've been researching non-stop the dangers of attached garages, and I'm fearing the worst for myself with long term exposure, such as cancer risks, CO poisoning, etc. I have a CO detector and I was planning to get an air purifier for my room and weatherstrips for my door since there're gaps on it. But, I'm not sure this is enough to alleviate my concerns. The one positive of the room is that it is isolated from the main part of the house/noise and does have great temperature control, with a separate, zoned thermostat for just the room basically. It's questionable that the room is really built to be a bedroom though: it seems to be more used as more of an office or storage area than anything.

How founded are my concerns? And how do I get over some of these anxieties? I lived here for \~8 months without having these anxieties, but it'll be difficult to enjoy life when I think I'm constantly in danger to my health when I sleep, which is a large portion of my life. It's almost like I've opened pandora's box of anxieties here. Is this worth moving for soon (lease is up in 8 months)? Or should I focus on improving the air quality in the room? I do like living here otherwise, like my roommates, etc, but I'm just highly anxious over this garage issue.
