Do you remember when you finished high school? There was this very specific feeling of closure that came over me. That's it, there is no more of this in my life. The feeling only comes when you are separated from a thing you feel attached to; school, job, bad habit, etc.
It's particularly interesting feeling to me, because it's liberating & filled with happiness, but it's also a bit melancholy. This thing won't be a part of your life anymore - you have bigger & better things ahead - you've moved on.
Maybe you'll cross paths with some part of it in the future & share stories / updates, but if not, it's ok because it was meant to end in finality.
