Dear [Friend],
I have noticed that you have been feeling down lately and I want you to know that I am here for you. I may not fully understand what you are going through, but I care about you and want to offer my support in any way that I can.
In times of struggle, it can be helpful to turn to scripture for comfort and guidance. One verse that comes to mind is Psalm 34:17-18, "The righteous cry, and the Lord heareth, and delivereth them out of all their troubles. The Lord is nigh unto them that are of a broken heart; and saveth such as be of a contrite spirit." Remember that you are never alone and that God is always listening to your prayers.
I also want to let you know that I am here to help you in any way that I can. Whether it's just being a listening ear, going out for a walk, or helping you find professional help, I am here to support you.
Please know that I care about you and want to see you happy and healthy. You are a valuable and loved individual, and I believe that there is hope for brighter days ahead.
Take care of yourself and know that I am here for you.
With love and prayers,
[Your Name]
