Moving and happiness

I was listening to Dr. Dobson's focus on the family radio show, which just happened to be on the subject of woman coping with a move. In the fall of last year my Dad moved my family from our happy home in Maine down to Pennsylvania.
I had and indeed at many times am still having a hard time. I miss what is comfortable, I miss what I know, what I love, what is familiar.
Dr. Dobson was telling the story of his wife when they moved to Colorado. The day she was standing in front of the mirror putting on her make up and the Lord told her "I'm not concerned about your happiness but your being in my will."
It hit close to home. It is something I know in my head but my heart has a hard time connecting with.
It truly is not important to God that I am happy, but instead that I am fulfilling his purpose by being in his will. I cannot think of one example in the Bible where someone lived a wonderful happy life. Instead the story were all plagued by hardship men had to overcome.
I have heard people say of course God wants you to be happy or else he would not have placed that desire in you. That is ridicules. I also continually have the desire to sin, to lose my temper. Does that make it all right, because the Lord has placed this desire in me.
Paul says I must die to myself daily, meaning the things I want, my desires, my selfishness. Is it difficult, yes. We cannot do it on our own, and the Lord means for it to be this way. We must learn to completely depend on him.
