At the best of times, I really hate making big decisions. I think, overthink, and then think some more before finally pulling the trigger. (And then usually I spend a few days wringing my hands over it.) This is my struggle, and it is real. But even if you happen to be comfortable and confident making decisions, there is one time when you want to avoid making any big, life-altering choices — and that is after a breakup, when you are emotionally raw and maybe even a little impulsive. The big decisions to avoid making after a breakup are any with major long-term effects. Now, that's not to say you shouldn't trust yourself to make big choices. You should absolutely feel empowered to steer your own destiny. I'm just suggesting you give yourself a little window of time to heal your broken heart, and if after that you still feel like moving to Thailand or shaving your head, then do you, boo.
With all that said, if you just so happen to be fresh off a breakup right now and are thinking about making any of the following oh-so-drastic choices, hold off a bit, because this moment, right now? Yeah, it's not the time.
