Sure! Here’s a rewritten version of your message in proper English:
"Hey, I just woke up thinking about you and wanted to check in. Are you really okay? You know how I feel about you, but that's a conversation for another time. Please take care of yourself and your loved ones. You've been through some tough times, and you’re still facing challenges, but I want you to know that I believe in you. Even if I'm not around anymore, my belief in you will remain. You are the strongest person I've ever encountered in the entire universe, and I'm truly grateful for that. Take care of yourself, alright?"
