My life...

Many nights I have cried, wondering what tomorrow will bring, however, I have faith in god, I know he will bring the peace of mind I need. . .
Life seems so complicated sometimes I feel like giving up, the more I try to live better, the more obstacles I come across. . .
People don't make it better or maybe it is me, who doesn't understand, who doesn't know how to live or who really doesn't care. . .
I feel like I have done nothing, I'm tired and upset. No one seems to see effort I make, the sacrifices and the pain. . .
I try so hard to live in peace as soon as I think I made it, I'm backed against a wall, I look for a way out, but I see no doors. . .
Why is it so hard for me to see the light?
Am I blind to reality or is this the way I'm supposed to live my life?
