First time leaving home

Hi guys. I'm a freshman at a college in Davao. Just last week, my parents came with me to help me adjust to the environment and to buy some essentials. And just that Saturday, they left. And ever since then, I've been feeling this pain in my chest. There have been many times were I'm just staring at my phone waiting for their call, or just stare at the walls of my cramped boarding house, noticing how disgustingly quiet it is. I feel so alone in this world now. Now, I have to worry about things I normally wouldn't. I have to do my laundry all by myself, I have to cook and clean by myself. I have no one to talk to the whole day. And when I go to school, sure, it's noisy and there are people you can talk to, but when I come back to the bh, the comparison is so scary. It feels like I'm all alone again.
