Try your best to have clear understanding before you are committed! 😉
Being worried, as you mentioned is hard for you to take; but, there are solutions. In this case obviously you will need indirect hints.
This is going to be a very sensitive task for you to do. Therefore, here’s a number of suggestions to be able to avoid confrontation or direct advice:
* You can suggest that you heard a program over the radio or a podcast that was talking about how to solve the sleep deprivation issues. You can put it as a chatting subject as if wondering if your relative had heard it or not.
* Another method is to come up with a story about a friend who has problems with sleep. Maybe s/he would realize that he has the same problem and start talking to you about it or at least shows some interest in knowing about the solutions that are used by your imaginary friend.
* You might be able to seize an opportunity when your relative is in a good mood, then you can watch some documentary asking him to help you in understanding some parts of it.
* Of course you can come up with your own indirect method of communication and try until you deliver.
It is great to help others especially family members. Maybe one day your favor will be returned with more appreciation than what you can imagine. 🙄
