I must know, but I dont know

I know from my past experiences that sometimes out of nowhere of your expecting mind and heart, somehow you land in a sad situation where you dont want to bid a goodbye, but you have to. I think does this makes us strong? Does it makes me strong when I have so much to say, but I cant make the other person realise that, and though your head and mind wants to convey too much, you have no option other than to realise that you have to come to peace on your own, and not after the other person listening to you.
