LPT: Go to the doctors with your parents or loved ones, be a team. Ask questions and ensure they communicate their sytomyoms and follow up accordingly.
Especially if there is a language barrier or they're are known to be busy .Doctors can be scary and time consuming . Having a buddy can let you look out for one another. Being a team ensures they won't miss any details of what is bothering them . You won't let them brush off any details as not being a big deal. And you can be on top of them so they do their follow ups and get the proper treatments .
Same goes with yourself find a buddy or SO to go with you and you will go with them.
Edit if you cant go with your parents ensure they have someone to go with them . Take out their buddy to lunch if you have too .
Edit 2: Gah title gore . Sorry typo.
Edit 3 : my dad would probably still be here if I knew this. I hope someone won't make the same mistake as me with their loved one.
