I get it. You're probably sick of seeing all of those Facebook posts, tweets, and Snapchat stories of an all-black background and some super passive-aggressive message typed out. You want to go back to wasting your day away scrolling through cute pictures of puppies and really awesome sunsets, and clearly seeing someone complain on social media doesn't have the same effect.
Some people may not be like you and are able to get over things super quickly. Sometimes it takes someone some time to process what just went on, and even more time to articulate that super well-written, passive-aggressive subtweet. By someone magically turning to me and saying "get over it," surprise surprise, doesn't necessarily make me want to get over it. Instead, it makes me want to be passive-aggressive and do the opposite... Well, not me. But OK, let's be honest, a lot of us do that, and if you don't, you're probably lying.
The thing with emotions is that they're pretty unpredictable and uncontrollable. I don't think you try and make yourself cry on purpose just to feel sad, and well, if you do, more power to you. You don't necessarily control how you feel toward someone or something, which in turn just complicates this whole process even more because that's precisely why no one really knows how you feel in return. Feelings and emotions just happen. Just like drinking a whole bottle of wine "just happens." But really. There is no magic switch that turns off your unhealthy and obsessive thinking patterns.
No matter how much you try and stop thinking about the boy who broke your heart, or the death of a loved one, those thoughts will always be there. Now, they may not be as pervasive and morose as before, but they will always be there. And I'm truly sorry if I'm the first one to break that to you.
No matter what you tell someone, even something as ignorant and blatantly annoying as "get over it," you will never be able to fix them, or fix how they feel about certain situations. Some people heal in days, some in months, and some in years, and a simple "get over it" isn't going to expedite the process.
When someone confides in you and says they are hurting, it is not up to you to decide when they're not. Rather, it is your job to help them and encourage healthy coping strategies, not dismiss their feelings with a common saying you don't care to think twice about.
Telling someone "to get over it" is a complete dismissal of their feelings, and just because you think it's time for them to stop being upset doesn't mean it's right for them.
Think before you speak, or before you subtweet. It could save a life... Or two.
