What goes up must come down

My demeanor started off on a flat line.
Life was mediocre and everything was just fine.
It could be better, or it could be worse.
Listen to the plea in my verse.
A little kindling started the flame.
It burst into a fire that's hard to tame.
A gush of goodness came over me.
Whenever it was just me and he.
A strange turned to a crush.
A crush revolutionized into a lush.
Like a bee pursuing a flower in lust.
Woe is Me! How sad to foresee.
This ending in pity.
For what goes up, must come down.
And if it ends my world will frown.
Alas! It shall be a travesty.
One more tragedy to add to my downer dynasty.
It was all love like Barney & Friends.
But If all good things must come to an end.....

At least for now can I still pretend?
