Am I being Selfish?

Me and my best don’t see each other too often during the school year because her college is almost 2 hrs away. We have been best friends for 10 years and In high school we hung out more of course because we went to school together. We usually do a good job of speaking once a day either through text or FaceTime. The past couple months she’s been going through some mental health issues so lately we have been going days without talking as much and I’ve given her space and have tried to support her the best I could. However, I feel confused because on Snapchat I see her post that she is at parties every weekend and I’m happy she’s enjoying herself and her college experiences. It makes me feel weird that the past couple months we’ve been distant and barely speaking cause she said she’s going through stuff but I see her socializing with other friends at parties. Am selfish or ignorant for feeling some type of way ?
