yes you should bother bottling. Often times immature, uncarbonated beer tastes bitter to me too (especially IPAs) but then after conditioning, carbonating, and cooling down to serving temps, they come out wonderful.
You'll read on here to never dump a batch. This I disagree with - for example, if you pick up fusel alcohols by fermenting too hot, toss it. But time heals a lot of bad beer. As Mike M said, if it doesn't improve with time in the bottle (at least 3 weeks) tell us more about what the "nasty" flavor is so we can help identify where you went wrong, how to salvage this batch, and how to fix the problem so you don't repeat it. Again, I bet this one works out for you with nothing but another few weeks of waiting
