Lonely....

Sometimes I find my self walking with my head downwards and with a heavy backpack..
When I look up, I will see the dead end and somehow when I turn to walk out of the dead
end, I see another dead end like I am enclosed in this place with little breathing space..
in darkness.... I cannot cry out or even hear myself..... all I see is the replay of an image..
A enclosed heart with steel covering it and a rusty old looking lock by its side....
No matter how I touch it... It has no way of opening... Why.....
Is it the fear that encloses me or just the littlest things that I can't seem to let go...
