Decisions

I asked myself if I've made the right decision every here and there in part of my life and the thoughts are so painful. Every decision that is made, somebody gets hurt, torn apart or fall. I asked if it was the right decision I made, months after making the decision, but how do you determine if it was right or not? Till now, when I look back, I'm still unable to tell myself confidently that I've made the right choice.
Sometime it feels like these thoughts are killing me from within. I'm like searching for a simple answer yet its so difficult to be found. Where do I even start looking for it? Who is able to give me the answer? The people that I've hurt? The people who were affected by my decision? or those who knows what has happend? All the answer that I will get are just answers from every different individual opinions. There is no way to judge right or wrong.
People always say, as long as you feel happier now, you have made the right decision. I might feel happier now, but few months down the road I might not. Or I might not feel happy now, but few months later I might feel so much happier. So did I make the right decision? Here again I asked myself. So many doubts, so many questions, so many uncertainties yet no answer to be found. They say that the answer will show, it's just a matter of time. As time goes by, the thoughts get heavier, the doubts I have for the decision I once made grew more, the feeling grew colder.
What to look at before making a decision? The current situation or the future stimulated/assumed situation? We don't know what will happen in the future but yet a decision has to be made now. How do I make sure I will not regret the decision I've made in future?
To be frank, I've questioned myself about some of the decisions I've made. They might have made sense at that point of time, but now they seem like it's not the choice I would wanna make again. Yet I can't turn back time and continue life from where I wanted. That part will then turn into a regret.
Every decision to be made is a heavy one. I've cried, I've smiled, been through heartaches and lots of crap. But one thing I learned, no matter if it's right or wrong, the earth continue spinning and the sun still rises. No one's gonna stop for me and my doubts, everything in life still goes on. I have to still carry on walking down in life and the only thing I can do about the decisions I once made is think back, nothing else, unless I can turn back time.
Be it fate or destiny, if it's meant to be, it will be
