Separation Anxiety

After we moved to a new country last September (2018) I began to experience separation anxiety; I had never felt it before. When my parents went out I would begin to tighten up and get panic attacks occasionally. Sometimes I couldn't breathe. I would get these awful images in my head, afraid something bad had happened to them. I didn't have a phone back then and we didn't have a home line so I couldn't contact them. It's gotten better now, and I still get worried and anxious at times but it's been a couple of months since I had a panic attack.
