Why am I not pleased with the results of my istikhara

The istikhara dua goes like this... **“O Allah, I seek Your guidance [in making a choice] by virtue of Your knowledge, and I seek ability by virtue of Your power, and I ask You of Your great bounty. For indeed, You have power and I do not have power, and You know and I do not know, and You are the Knower of the unseen.

O Allah, if You know that this matter (then you mention your need) is good for me in my religion, my livelihood, and the end of my affair (or: in the near and distant future), then ordain it for me, make it easy for me, and bless it for me.

But if You know that this matter is bad for me in my religion, my livelihood, and the end of my affair (or: in the near and distant future), then turn it away from me, and turn me away from it, and ordain for me the good wherever it may be, and make me pleased with it.”**

I made istikhara for a particular situation in my life a few months ago, and things didn't turn out to be the way I wanted them to be. (I AM NOT BEING UNGRATEFUL!!!) everything happens for a reason, and I know Allah swt wants the best for me. It's been months that I've made dua and the last line in dua says make me pleased with your decree, but I still feel bitter and unhappy about it, and I still want to make dua for that particular thing even thou it has been removed from my life thru istikhara.. Idk if it's my nafs, emotional attachment or js...Allah putting dua in my heart for this thing again.... It's just,, been months and I feel so sad about it.
