As both a friend and a son of two people that were diagnosed with terminal illnesses, here is my advice to anyone dealt that same fate

To those who are diagnosed with a terminal illness

Use what you have while you have it. It will all be gone faster than you think
Tell the people around you that you love them every chance you get
Don’t waste your precious time being negative about things you can’t control
Nobody can tell you exactly what is going to happen to you on your journey. Just try to control what you can and go with the flow
Hug... A LOT
Smile as often as you can. It’ll make you feel better
Be brave. Courage is the most important thing there is

To those who do not have a terminal illness
