I know what you're talking about. I am very indecisive as well. It is so frustrating! I have a tendency to over think things way too much (various options, outcomes and paths, etc.) and when this happens and I can't pick, it leads to ultimately not acting at all... which only serves to frustrate me more because I then feel guilty that I chose not to do anything and think about what might have come from making a choice or taking action. I get angry at myself for this and it renders me incapable of doing much else other than obsessively think about my decision of indecision.
