well i thought poems are to express your self right most are depressing and i thought thats what poems are dark and depressing or would you rather me write things like this

i was driving in my pick up that was blue
i drove by a girl who had no clue and a
big gulp full of mountain dew i stoped to see
if she was ok i woke with no kidney and found
out she sold it on ebay
or somthing like this
my life is happy and chipper
good and fun i like to run on blue berry hill
i talk to my dog marry who makes me
feel good and i smile every day

should i write like that or write how i feel? because i try and nobody even cares i do what i have to and i got to bed thats my life and i've never been to the ocean so i don't know what its like
