Homesickness is the #1 symptom for kids freshmen year. Homesickness is a totally normal experience. You are not alone there. As for the depression, meet with a counselor. That is what they are paid for and more students should take advantage of them. Hang in there. If all you are needing to hear is that you are not alone then there are literally a million freshmen across the globe that feel the same way you do. I did and my kid feels the same way who is a freshman now.
