Though I am married according to my will now I am not happy with my husband. I want to know if this is some kind of divine punishment due to the fact that I was excessively picky to choose a boy when my parents facilitated suitors for my marriage?
It can be very difficult to judge whether something happens due to divine punishment, versus due to natural cause and effect. It is often better to look at the situation in front of you and see what you can do about it.
There are often surprises after marriage, and being picky does not guarantee that one will be happy. People (especially younger people) also often don't know what they want until they find out, through experience, what they don't want.
Anyway, I agree that it would be good to identify why you are not happy, and see if there is anything you can do about it.
All you can do is your best, keeping in mind that a marriage has two sides, and if the other person is unable or unwilling to try to improve things, you can't fix it alone.
With du'as!
