Why?

There are so many questions that i wish to ask.But most of the answers to these questions are ambiguous. Some of them are my past experiences. Some of them are what i've seen others have encountered

ex-post regrets and ex-ante regrets. No matter what u do, u regretted of either doing it or not. Why? Secondly, when some people are around you, you may have not appreciate their presence that much and when someone has to leave you start to feel sad, remorse over not appreciating their presence when doing it now is hard because time flies. Why? Thirdly, some people are decisive that they know what's best and what's not and that there are some who are always in doubt whether to commit in something or not to. Thinking about it to and fro, front and back. Often they do not make a wise decision out of it. Why? Then, there are certain people whom have feelings (good or bad) may not have the guts to tell the counterparty. Why? Nevertheless, there are some people who wants to do something but arent sure of what they wanna do because they are unsure about their feelings. Feelings like holding back, but at the same time could not afford to waste a chance, thinking of letting time to tell. Why?Lastly, there are certain people that when they are so into each other that sometimes may not be together for some reason which god knows what. Why?. Last but not the least, there are people whom think that they may let time tell if in any way they can be together later which as a consequence of incapability to put aside this commitment. Why? Does time really tell?

I do not know. I love letting time tell, because i think this is the only way or in fact the best way. I have more questions to ask as days pass by but what i could do is just keep it deep inside my tender heart. I have not been doing good lately mentally.I'm not saying that i am crazy or what but this is how i feel. There so many conflicting issues to think about, contradicting issues to tackle, taking up commitments and compromising. What does all these takes?
Honestly I Don't Know!
I am still finding the way out of this. and i guess to most of you who are reading this u may feel the same way too because we have something in common. We are homosapiens.
