i am tired of everything

Anything feel tired of their life but your partner can't even understand it? Maybe because they never felt what depression is like. Instead of understanding they tell you many things that you should be grateful like you can eat 3 times a day. but they don't understand what's going on your mind. they thought you're lucky but i don't how to explain how i feel on my life but i feel miserable and i don't why. i just want to evaporate. then people left you when you needed their understanding the most. they ask you to force you to tell them how you feel. i really hope its that easy to be normal and share what's on going on
