Normal to be sad over this?
This summer, my friends and I have been talking for hours at night on Skype. It's gotten to the point where I look forward to it all day, and it simply gets me through the day sometimes. Well, lately most of my friends have been talking without me and with someone else instead. It's been upsetting me to the point of tears at times, as it feels they're "replacing me". Is it normal to get upset over something like that?
