When we are physically compromised, we have to get used to things like not having enough energy, or being clumsy where once we had grace of movement, and other things. PD stresses the body in ways that can cause a worsening of the symptoms that you have.
Life these days is like that. We are under all kinds of stress. We have so many worries, we don't even really remember when it wasn't like that. But don't get discouraged! We are at war.... At war with PD; at war with rulers, powers, and world forces of darkness. We war with spiritual forces of wickedness in the heavenly places (Ephesians 6:12).
We are going to get tired. Let me encourage you, Reader, keep striving to finish the race! We know that God is the Victor and in the end, when all the battles have been fought, and when all of the dust has settled, the Lord's banner will be seen flying high. He wins! And so do we, if we belong to Him.
We will not strive forever!
God has put you here where you are, at this particular time for a reason. Fight for all you're worth! Think of the prize set before you. Jesus is coming back very soon. Having that hope, fight your battles with single-mindedness. Hold back nothing, but spend yourself wherever you are. We will soon rest our weary selves and we will fight no more.
