Your dark room
Being misrable sometimes is your choice not something you are forced to have. It is just triggered by external environment. Then, it is your role. You enter you dark room bringing with you all sad memories, list to sad music, remember all bad events, see everything is black and how you can see colors in a dark room.
After sometime, it will be like an energy surrounds you. Brings all bad feelings to you and all people arround you. It is true that feelings as diseases, they can spread.
Inside the room, everything you see or say will be bad. It is a environment now not just something happened. Everything you feel as well. You will see only dark part because no light is there. You will hear every word as insult even it is sweet. You will feel hate in every feeling even it is love. You will see every seen is a fire even it is a pretty garden.
Dispiration is next and very closed to this. That when you lose hope that any thing will change and that will be true as long as you are inside that room, nothing will change. Room can not change because it is the room of darkness. To change that, you have to leave the room. You have to open the light or generally, you have to do something. Nothing changes with itself, you have to do something to change what is arround you. And even you do something and nothing changed, do not repeat same technique to get same result, do something diffreent. That is only if you want to getinto light.
