Step one.
Open the top drawer of that dresser dad gave as a moving out present.
Step two.
Look for the keys. Yes, the one marked Yale. That tiny one.
Step three.
Under your bed, find that metal box you bought as your money safe.
Step four.
Open the box. Insert the key, twist, open the box.
Step five.
See all the memories and money you kept in. Find the notebook labeled “unsettling".
Step six.
Read everything you wrote. Read them until you remember. The exact moments, people, places, and feelings. Read every decisions. Read every mistakes. Read every regrets.
Step seven.
Feel everything. Feel the hate, love, indifference. Feel the feeling or the lack thereof.
Step eight.
Admit to yourself that everything is unsettling.
Step nine.
Return the journal. Lock the box.
Step ten.
Make tea. Drink it.
Step eleven.
Relax. Calm down.

It's settled.
You finally settled it.
There's something unsettling.
