On ambiguity

So when you want to understand something that is ambiguous and you cannot get a verbal explanation- what exactly do you do? So you want something- you can't seem to get it, and you can't seem to get a strait answer- but it's like you have enough of an answer to think abandoning it would be proper- but not enough to actually change your feelings and cause you to give up hope? Introspection will only get you so far- but I am prone to it. But it is not enough- knowledge is never enough. You always need something more. And you never have all the information when you make decisions and choose to act or not act on things- yet you make these choices every day. So when you are in conflict with yourself (or so you think- even though it may be just conflict with circumstances)- how do you address your feelings and act with a seeming lack of information. Giving up is hard.
