Have you ever experienced losing friends? The kind of situation that they are present in your life, but you just can't feel them. That moment when they are slowly drifting away. It starts with them planning for something, without inviting you. Sometimes, you initiate to invite them but for oh-so-many reasons, they just can't be with you. This is the time when you will start to feel valueless, unwanted and left out. Time will come when you don't know them anymore, as they had changed. And you have changed, as well. Unfortunately, you and your friends grew out in different paths. And that my friend, is actually normal.
Could it be that you just became too sensitive or too serious with life? Or maybe you could just have different interests now. Their jokes are not your jokes anymore. Even though they are the people that you have known for the longest time and x-number-of-years, still things have changed. They were once the people that you text first whenever you want to hangout, but now seems like you don't know what to about with them.
It's normal to grew out from your friends. It could be that the universe is telling you to be mature, to grow and go out from your safe zone. We really can't force people to stay in your life. If people want to stay, let them. If they want to go, let them. Learn to value what you have and what you will have. You just can't make everyone like you. But whatever happens, don't hate yourself just because they don't like you. Instead, appreciate your individuality. Find your tribe, they could just be out there looking for you too.
