Moving out: dealing w/ depression

Hi, I’m 18 and moving out to go to college about 2 hours from home. The problem is I have pmdd and also struggle with depression which gets worse during the winter. The only healthy coping mechanism I have is being close to friends and family, which is kind of hard to do when I’m so far away. I’m really nervous about how I’ll deal with my home sickness, depression, and suicidal thoughts...any tips?
