A person once told me, that there are two different causes to feeling loneliness

The first one is physical solitude

it's when walls obsecure a prisoner's vision, hearing and movement

Effectively isolating them from the outside

They can find a way out of there by using a key or a device

but

that's all useless if the person doesn't want to leave

And that's where the real prison lies

It's the self

The self can keep a person within that prison by can convincing them that there is no way out of there

It can comfortably keep a person in there forever by using adaption

Find the peace within the silence, it says

Find the stability within the plain Greys, it says

so the prisoner remains despite having available materials for a tool

The self can form walls of emotions that change frequently, they are so flexible and uncontrollable that the keys are different each and every time

Making it seemingly impossible to leave

Making it seemingly impossible to connect with others

If I don't find a way out of this, the feeling of being alone despite being surrounded by friends and loved ones

Won't leave

And I'm willing to do whatever it costs to become truly free.
