Crack my code

I don't know if I'm losing it
or if i got nothing to lose
i don't know but mind battering thoughts
have left me with a bruise

should i let my words escape from my mouth
without any loss of thought
or should i ponder the meaning of
happiness cant be bought

life was so much easier
when you explained it
but since you... my heart is gone
I'm trying to figure out how i obtained it

if you can figure out this cryptic message
then relieve me of this bruise
explain to me how
your the only thing that i have to lose

P.S i just wrote how i felt about some one special and it came out like this if you can understand it then let me know what you think.
