Dearest [Friend's name],

I hope this email finds you well. I'm writing to you today because I've been thinking about you a lot lately and I wanted to check in on your health.

I know you've been going through a lot lately, both personally and professionally. I just wanted to let you know that I'm here for you if you need anything. I'm also here to listen if you just want to talk.

I know you're a strong person, but even the strongest people need a little help sometimes. Please don't hesitate to reach out to me if you need anything at all.

I'm also sending you this care package with some of your favorite snacks and drinks. I hope it brings you a little bit of joy.

I'm thinking of you and sending you all my love.

Love, [Your name]

Sure, here is an email you can send to your friend to ask about their well-being:

Subject: Checking in on your health

Hi [friend's name],

I hope this email finds you well. I'm writing to you today because I haven't heard from you in a while, and I'm starting to worry about you. I know you've been going through a lot lately, and I wanted to reach out and see how you're doing.

I'm especially concerned about your health. You mentioned in your last email that you've been feeling under the weather, and I'm worried that you're not taking care of yourself. Have you been to the doctor? Are you getting enough rest? Are you eating healthy?

I know you're a busy person, but your health is important. Please take some time for yourself and focus on getting better. If you need anything, please don't hesitate to reach out to me. I'm always here for you.

I hope to hear from you soon.

Best, [Your name]

I hope this helps!
