<human>: Hey guys,

I moved to a new apartment, 3200 Km away from home on January. I was sharing that apartment with 2 housemates but they both moved out while I  was taking a 2 month vacation to go see my family.

Since I came back, I've been feeling more and more alone, specially after my neighbors also went on vacation and the only interaction I have with people is when I go to my classes from 8:30am to 12:30. Other than that my life feels replete with solitude.

9 months ago I was going out with my best friends, getting drunk and partying at least twice a week. Today, I live in a kinda big but spread out city and I barely know anyone my age. It was a really rough change. I stopped doing many of the things I was used to overnight. Everything was so drastic that I don't feel like anything like that ever happened, and that's what I'm trying to express here. I feel like my past is just made up. Nothing ever really happened when I was 10. Nothing really happened when I was 14, 15, 16 and 17. Nothing happened 9 months ago. The event I went to this Saturday never really existed. Yesterday is something I made up.

I feel like I'm going crazy. Every time a memory about anything comes to my mind I feel like I'm just making it up. Like if it were one of those movies where the main character has made up a fake life and then suddenly becomes lucid and notices how what he thought was real is actually fake. But then again I know it's not fake because I'm frequently contacting some of those friends I used to hang out with and most of my family. There are pictures and videos. I have scars from when I hit that tree while riding my bike 4 months ago. Everything has evidence of being real, but it just doesn't feel like it.

Anyways, I really hope that when my new housemates come back I'll be able to think normally again and accept the past as something that did really exist and not something I just made up. I feel like this is one of those "it's your brain just blocking what you dont want to remember" things.

Summarize the given text in a few sentences.
<bot>: My life-style changed drastically and I started to feel like what happened before that change never happened. It has developed to a point where I doubt on the existence of a yesterday.
