How do you tell your family you have tmau?

When i first got tmau or when it became bad we went to every doctor and then my family couldn’t smell me. Now they do and its been 8 years. I dont know if i should just save money get tested when i know i have it and then tell them. Or should i tell them now. So i can get the money faster and have them a aware so they can be apart of it with me. I know i will test positive its just a matter of doing so.
