Like my Shadow in the Sun

My care is like my shadow in the sun—
Follows me flying, flies when I pursue it,
Stands, and lies by me, doth what I have done;
His too familiar care doth make me rue it.
No means I find to rid him from my breast,
Till by the end of things it be supprest.

This part of the poem I believe she is talking about her love. She will always have that love, and hates that she has it. She feels that she must surpress these feelings, to be the queen and rule her people. I can relate to this as well. To love somone so intenly, and want to be loved back. But that love isn't whats right, or whats best. Try to run and it follows you, try to chase, and the love is gone. She says no means to rid from my breast, she can't get rid of her feelings. Of course not, means of the heart don't just come and go on command, so she surpresses these feelings. Burrying them deep into her heart, only to feel the agonizing chase in only her heart.
