Wake up call
We are such suckers for pain I tell you, that if someone is painless or worse, happy without us, we try to guilt trip (or guilt trap) them within our sob stories, holding them responsible for being content without us, while abandoning us alone in a sinking depression of memories and miseries.
We were addicted to them and now we're addicted to feeling the pain, they've allegedly left behind. We shift the blame on to their absence, cause it's easier to believe we can do nothing about it and continue to cosily slump.
And the way we have been slouching so far, rolling in self pity, cutting ourselves with rusty blades of self loathe, pushing away our dreams behind a screen, might as well turn on the front camera and take a good look at ourselves. Do we even like this unkempt, abhorring and boring version of us? Then why would anyone else?
Who are we kidding? Nobody's coming in to give us a hand. Nobody owes us happiness except ourselves. It's our own responsibility. If we need help in finding it, we ought to ask for it, not wait for it or shun it when it's given. But for God's sake now get up, dust off the dirt and wash away that gunk off yourself. Drink some sun, go for a run, eat better, dress smarter, and force your face to smile more often. As clichéd as it may sound, happiness only likes the company of other happy people. So, pretend if you must, but trick that bugger into being your guest.
Ironically, the only way to get someone back in your life is by learning to not need them, to be happier and better without them. And once you've learnt that, you won't actually remember to want them anymore.
