I am a 19 year old Female, currently in college and seperated for a prolonged period from my parents, with whom I have a close relationship, for the first time. I've also been in a relationship for almost 2 years that is sometimes very stressful. I have a history of depression and took Lexapro for about 6 months when I was younger. I don't believe I've ever had a specific panic attack, but my most common anxiety is over analysis of a situation. For example, if I would arrive late to my house, my parents' car would be gone, and they hadn't left a note or message, I would start to visualize and worry that they had been kidnapped, that they had gotten in a car accident somewhere, that they were dead, and it's extremely distressing. Also, sometimes when I have free time and I'm very bored, or I can't fall asleep at night and my thoughts wander, I have visual thoughts about my parents, friends, sister, even PETS being killed, and many times it's a fantasy situation where I have to choose to kill one of my loved one's a let another live. I can't halt these images, and I'm not sure if I have an anxiety disorder or simply an overactive imagination. Either way, I can't deal with it anymore.
