My dear friend,
I was truly sorry to hear about your recent illness. Learning that you haven't been feeling well has been on my mind, and I wanted to reach out to send you my warmest thoughts and deepest concern.
Please know that you are missed. Your absence is felt, and I sincerely hope you are being kind to yourself, allowing your body the rest and quiet it needs to heal. Don't worry about anything else right now—the only important task is your recovery.
I am holding you in my heart and sending all my positive energy your way. I imagine you surrounded by comfort and peace, with each new day bringing a little more strength and wellness back to you.
Wishing you a gentle and speedy recovery. I look forward to the time when you are feeling like yourself again and we can share a warm cup of tea and a good conversation.
With the most sincere care and warmest wishes,
[Your Name]
