i had bad day today

i had a bad day today. i don’t like mood swings.
i don’t like to feel vulnerable.
but i don’t wish to be numb either.
increasingly, i find that it takes a lot for me to be happy and takes very little for me to be unhappy; when really, it takes very little to be happy and there is little to be unhappy about.
how much does happiness cost?
i wonder. if you have it, will you please share some with me?
on bad days like these, i just want to go to bed and end the day early.
tomorrow’s another day.
yours.
