When I was in my freshman year of college, the best thing that helped me with my homesickness was turning to my bible and reading encouraging passages.
Psalm 91
"He will cover you with his feathers, and under his wings you will find refuge; his faithfulness will be your shield and rampart"
Being a college student, you face many obstacles. The biggest obstacle would be moving away from your family. Whether you like your family or not, they are a part of you and you will have to learn to fill their place for you while you are at college or moving out into the work force.
'His faithfulness will be your shield and rampart', I took this part of scripture as meaning that with faith in God on your side you will be able to conquer any tasks in front of you. It was comforting to know that even when I was alone or scared, God was protecting me.
Psalm 121
"The Lord will keep you from all harm-he will watch over your life; the Lord will watch over your coming and going both now and forevermore."
Every day your parents watched over you. Since you were born, your parents would make sure you didn't get in any physical danger and as you grew up, your parents never wanted to see you get emotionally hurt. It's a weird feeling to move out of the house and not have that protection over you. But with God, you will always have that protection because 'he will watch over your life' always.
Give your heart to God and turn to Him and He will make you feel safe and secure as He watches over you.
