I just wanted to write and let you know that I've been thinking of you lately. The last few times we've <seen each other/talked>, you just haven't seemed yourself. I hope nothing is wrong and that it's all in my imagination. If, however, there is something wrong, I hope you'll let me know if there's anything I can do. You know that I'm here for you, for anything. Any time you need a hug, a kind word, a shoulder to cry on, or just a willing listener, I'm only a <phone call/letter> away. Please don't hesitate to call on me. What are friends for if not to be there in time of need?
Please take care of yourself, <name>. I'll be thinking of you and wishing you the best. I hope to hear from you soon.
