Unable to cope with High School's end?

Hello, my name is Daniel, I am now 23 years old. Its now four years that I finished high school (on june of 2012). Today I woke up, and the thing that I would be extremely happy about would be just to board my usual high school bus, get to school or some other place where all those friends would be together and just be there with all of them. And its totally impossible and I really do not know what to do.

My biggest effort to move on happened two years ago when I completely isolated myself from all people which were connected to high school so I could move on (in 2014) but its still not possible for me to do. Its like high school never ended and never will. What can I do?

My idea is to find a new collective but its just whatever people I find (for example in college), they are just not enough in comparison with those that I met in high school, and I can't be happy with them.

I know how you feel. I too often wish that I could go back to my old life. I want to go back to my home town, I want to see all my old friends again, I want to go back to a time when I was happier. But I think this is just means that at one point what we were doing was working for us, and now things aren't. Of course, we are going to want to go back. But the path to happiness is not searching where you left it. The path to moving ahead it exactly that, ahead, not behind. We can't go back in time, it's just not possible. Things are different now, but change can go both ways. I think you need to keep trying to move forward, find other things that make you as happy as you were in high school, or even happier. You have highs and lows in life, and it seems we're just in a low at this point, so it's natural to want to move backwards back into the highs but as hard as it is for me to say (because I have a hard time accepting it myself) we need to move forwards.

Hang in there buddy.

I became quite depressed when high school ended as well.

I chose not to go to college right away and it was amazing the amount of backlash I got from peers and adults. But probably the most depressing part was seeing all of your old friends, the people you used to see everyday, just go in their own directions. It was interesting yet depressing to see what people chose to stay in contact with who and who they chose to ignore. Pretty interesting in an anthropological sense.

High school ending is a huge shift. I think it is an unnatural one, too. Are all of these people suddenly supposed to just walk out of each other's lives? I'm not too sure, but also leaving high school can leave one with a bit of positive sentiment.... it is the first step into real life, adulthood... if you want to look at it that way.

When I finished my education with a degree in science, I kinda expected my life to change massively for the better. But nothing happened. Literally nothing. World had zero interest in my degree, my job remained $#%^ and I was quite depressed as well. It was like throwing a big party and nobody showing up. So I can really relate.
