I am 19 and I get anxious almost every day about someone I love dying, especially in an accident. It is taking a huge toll on my mental and emotional health. For example, right now I am terrified because my boyfriend is on a plane. I just can't stop myself. I always picture my loved ones in accidents, I always imagine everyone I love dying. It is like I am preparing myself in case that actually does happen. I get very anxious and sometimes depressed. It makes me sick and want to cry. Any advice?
