Lately ive been feeling an emptiness inside me and idk what to fill it with?

Usually the feeling to describe this with is nostalgia, but for what i dont know, i feel like i am so grateful for everything i have, my family, my friends, my health, all of the things God has blessed me with, but i feel a longing for something that is unclear to me, im sitting in my room bored to death, but its a beautiful day outside and everything is relatively right in my world i guess you could say, but i cant shake off this feeling, because i dont know what it is, i kindof always feel this way, i really dont think its depression, i have friends who i hang out with and try to make plans with and they love me but after everyone leaves my feeling isnt satisfied, sometimes i long to move to chicago where i go sometimes to visit my cousins and i usually feel so happy over there but when i come back home i feel like nothing i do can make me feel alright again, kindof like im constantly bored and can do nothing about it, i live in a boring town, and ijdk how to classify these feelings?????
