In order to take a look at paraphrasing this 14 lines, I am going to break it into 4 sections: 1. the first 4 lines, 2. the next 4 lines, 3. the third 4 lines, and 4. the last two lines.
1. During the lonely times in life when I realize how low I am in the eyes of men, my own eyes, and my own luck in this world, I pray to God and I curse myself.
2. I compare myself to one who has a better outlook, a better look, more friends, a better job, and better talents, wishing in my job and life I could have such things.
3. In the midst of these despressing thoughts about myself, I begin to think about you [insinuating a lover], and that thought lifts me up like an early morning songbird lifts their voice, making me want to sing praise to God.
4. The chance to remember how you love me makes my state much better than I thought it was and I would never want to change my life since I have you.
This is a poem about love and about how the speaker feels when he thinks about his love.
In the first nine lines, the poet talks about things that make him feel bad. He says that he feels bad when he has lost the respect of people in society and has become an outcast. He says that in such cases he cries out to heaven but his prayers go unanswered. At such a time, he wishes he were someone else.
But then he thinks about his love and everything gets much better. All of a sudden he starts to sing like a bird and sing hymns of joy. Then he would not switch places even with a king.
