I want to preface this by saying that my current roommate has only ever been kind to me and I would like to consider them a friend of mine. 

I've lived with enough people, especially in my age range, to understand that not everyone has the same standards of cleanliness. My current roommate, however, is making me uncomfortable with their use of our space. I have been fine with clutter and loose clothes for a while, but it's getting to the point where they don't clean up food or trash (as a side note, I also have a phobia of bugs which is causing me significant angst). I try to clean up their messes so as to avoid attracting bugs, but I don't understand if this is a social faux pas or if I am making the situation worse. The rational part of my brain knows I shouldn't have to tolerate this and that this behavior is disrespectful towards me, but my social anxiety is too deathly afraid of the consequences that might come from talking to them about it. I don't feel prepared to deal with confrontation as it's a great source of anxiety for me (but it seems I'm losing regardless of what I do). Any advice?
