My faith in God can bring happiness as long as it is healthy faithfulness and not an obsession.
My children and husband bring the most happiness.
I love music, all different genres, and I can sing the words to so many songs it is ridiculous.
I love to write. Even sad things that I write through tears are full of passion which brings a certain level of joy and satisfaction.
I love my best friends (I have 2) and that they have stood by me through the worst. They even visited me my last hospital stay.
I love my parents more than words can say. They take care of me as a child (which sometimes drives me mad). The same for all of my siblings (especially my sister).
I love long drives, long showers, and dancing in the rain.
That's all I can think of for now.
