Constant cycle

Everything is looking up.
I see things clearley now..
I kno what i have to do,
but i cant seem to fill these shoe's.
As soon as i go up,
and im happy. 
I fall back down,
and hit the ground.
Yes it hurts,
but I know what i have to do..
So I try to regain what little strength,
I have and get back up again.
Then try to find happiness again,
and it seems like everytime I find it.
I fall the next day.
it's a constent cycle..
it's like a ledge,
and im on the edge.
That i fall off everytime,
so then i just get up and climb.
Then cycle starts again.
