How to say thank you after asking for help?

Thanks for your help, brother. I will remember your kindness to me. I hope you can feel my sincere gratitude ... you don't have to thank me for my kindness. Please feel free to say hello in the future I really appreciate it． I really don't know what to do without you. Thank you for your help. Please accept my wishes.

It's really troublesome for you. I really don't know what I would have done if it weren't for you. Next time, if there is anything I can use, please let me know!

Wait, whatever.
