They call it the "Quarter-life Crisis."
What you don't recognize is that they are realizing that too, and aren't really cold, catty, mean or insincere, but that they are as confused as you. You look at your job... and it is not even close to what you thought you would be doing, or maybe you are looking for a job and realizing that you are going to have to start at the bottom and that scares you. Your opinions have gotten stronger.
You see what others are doing and find yourself judging more than usual because suddenly you realize that you have certain boundaries in your life and are constantly adding things to your list of what is acceptable and what isn't. One minute, you are insecure and then the next secure. You laugh and cry with the greatest force of your life. You feel alone and scared and confused. Suddenly, change is the enemy and you try and cling on to the past with dear life, but soon realize that the past is drifting further and further away, and there is nothing to do but stay where you are or move forward.
You get your heart broken and wonder how someone you loved could do such damage to you. Or you lie in bed and wonder why you can't meet anyone decent enough that you want to get to know better. Or maybe you love someone but love someone else too and cannot figure out why you are doing this because you know that you aren't a bad person. Getting wasted and acting like an idiot starts to look pathetic.
You go through the same emotions and questions over and over, and talk with your friends about the same topics because you cannot seem to make a decision. You worry about loans, money, the future and making a life for yourself... and while winning the race would be great, right now you'd just like to be a contender! What you may not realize is that everyone reading this relates to it. We are in our best of times and our worst of times, trying as hard as we can to figure this whole thing out. We aren't alone in their state of confusion...
GOOD LUCK TO ALL OF US!
