"what do you do when you have no idea
When your dying inside and you cant figure out why"
idea and why don't rhyme, idea ends in an 'uhhh' sound and why ends in an 'iiiii' sound.

"what do you do when you start to believe
that your whole life is one big scheme
what do you do when your moms abusive"
iono what scheme was supposed to rhyme with
~~~
"what do you do wen you realize its time to say goodbye
what do you do when you decide to take your own life "
also not a rhymed couplet
~~~
I wouldn't mind if none of the lines rhymed at all, but if you want to make a poem composed of rhymed couplets, then I think you should try to carry the format all the way through.
