Hey y'all. I'm new to this and I really need some advice. I'm 17 years old and I'm battling anxiety. I keep having chest pains and arm pain and back pain and just all kinds of pain. The main thing that bothers me tho is my chest pain and shortness of breath. I'm steadily scared I'm going to have a heart attack, but my doctor and counselor says it's just anxiety. Should I believe them? I'm just really scared I'm going to have a heart attack and die at a young age. Nobody in my family has had one though, so idk why I'm so scared.
