Insignificant changes in my life

After graduating I'm feeling strange myself. There is the second weekend, when I don't need early wake up and I have full saturday for my personally life. Unexpectadly I got a lot of free time. But if in that time I always complainted on my totally busy, now I don't know, what I want to do.
As a habit, we are meeting with my friends from President Program. But I think, it will not long time. Soon we will became boring for each other.
Except for my physical doing nothing, I have a void in my head, in my soul and in my heart. There are a lot of people (relatives, old friends,familiars, guys), who want to communicate with me, who want to meet me, who want to spend time with me. It is pleasure for me. But I'm not feeling the same. I love my alone life in my small world, when I never boring with myself. Some times I think, that I'm going crazy. Directly and slow.
In last month I though, when I have finished President Program, I will: 1....,2....,3... etc. I had a lot of plans. But now I want nothing. Every expressing emotions I consider now like a fool waste. Interestingly, how many time it will go on?
