what is what?

Do you ever just feel like you have no idea what the fuck you want? and then theres that saying you dont know what you got till its gone. like you regret that you didnt take that chance after its over, but im so curious, is that true? Maybe people just think they regret it because the opportunity is over. i mean for sure everyone is guilty for the fact that they are just not happy with what they have. everyone is guilty of that. me especially. its not a horrible thing its just a fact. in this sense i could be in a relationship tomorrow. or not and say im feeling awful about it but may not even be phased just subconciously think i am. like that blog yesterday? was i really that upset? or was i just upset at the concept of getting my heart broken? its the concept that makes sense to everyone and when reality sets in, yeah when reality sets in, THATS when we get confused. any thoughts?
