How to not be alone ?

Hello everyone I am 19F . I am doing my internship in final semester for a company in Chandigarh and my friends are enjoying in the college. I want to be in college with them as this is my last semester. I am here alone. I don't like anyone from my company nobody is near my age and all they speak and do seems fake. I am not able to understand their conversations. I just go do my work and come . I have a pg but the girls are busy and due to shortage one of the pg incharge sleeps is my room ( my bed) for 2-3 weeks only and she has a lot of restrictions. She is old when she does pooja she tells me to go out of the room. She sleeps most of the time so turns off light and she is taken whole cupboard I have kept my thing in bag only and everytime I require something I need to open My large suitcase which is kept below the bed. I know it's just the matter of a few weeks but I am paying a lot for it. Also she has a grand daughter , she is cute but she always enters my personal space. She just hits me and run even touched me inappropriately for fun. I don't know how to deal with it...I have never spent time with kids like this if it was my home I would have simple slapped but I can't here . I don't even know how to scold the kids. The pg girls are also way elder than me and they are always busy there is nothing i can talk to them about . I want to visit so many places in Chandigarh but I can't all alone I need someone. I have a boyfriend but he is also in college and busy with his friends and studies so I don't want to disturb him much because it is his last semester. I have a best friend too but she is also in college busy with her things I am craving to talk to someone like meet someone and hangout with them. I have never been far from my family. I am not liking anything here. I don't know what to do on weekdays I am super busy with my work and on weekends I am like this I don't know what to do may be I am not able to express myself with right words but I just want to screen and cry and then sleep.
