Leaving vacation tomorrow

My parents have been divorced since I was 4. My mom and dad live in two different states and I am in college in the state my father is in.

It was thanksgiving break so I took a flight to see my mother and it has been really fun! I’ve been here since Wednesday and it was great seeing all of my family members. My flight is on Sunday and I feel sad today. My brother also came to visit and he left today. Idk… I just feel sad. Not sure why… just feel sad. I feel like I’m empty. my brother left and I know I have to leave tomorrow and it makes me feel down... I wish I had more family members.
