Question: Hello, It all started about a month ago. I smoked marijuana and then had a severe panic attack. I am 22 years old female 5"9 200 pounds. I was told I had mitral valve prolapse years ago by my doctor, but then when I had an ultrasound of my heart the cardiologist said no. I've had blood work several times. Plenty times actually. But the only thing that was show was a positive XXXXXXX reading but then I was tested again it didn't show one. I have been bedridden because I feel like my heart is pounding out of my chest when I stand. It scares me I also have severe anxiety and recently quit smoking when this started. For the last two days I've been having pains in my left side under my rib cage, I also feel short of breath, but the shortness of breath has been since I've quit smoking. I also have agoraphobia. I am seriously worried about my health but I am also depersonalized and scared to go to the doctor again. I have multiple panic attacks a day. I am severely depressed as well. And I am convinced that I have something seriously wrong with me. I would like to know your best advice and thank you.
