Strange acting of my housemates...

Already a few days I never talk to my housemates, the serious one, my room-mate.
I dunno what's happening between us. Just felt that we never talk much nowadays.
Everytime when she's back from the college, I try to greet n talk to her but she seems doesn't want to talk much. Then, I just keep quite all the time. The circumstance is also the same with my other housemates. Am I thinking too much as I'm a pessimism person? I hope it's not the same as what I thought.

I know I'm going to leave here but I hope everything will be going on as normal as usual. The way they whisperring and closing the door in their room makes me feel sad. This is not what I want to see since I'm going to leave here, some of them dunno about this yet. I hope everyone will be happy like before I moved in here.

Ya, I admit that sometimes I really overthought about something, but this is what really I'm doing all the time. Everyone should know this, especially my friends. Although I know maybe something is going to happen but I'll not bother bout it too much as I'm not a busybody.

Friends are freinds. Please tell me whatever you can. Don't leave me behind. It makes me feel very very scare...
