The anxiety I deal with is exclusively focused on acute health concerns. Mentally, I am very happy, excited, and am immensely grateful for the life I live. However, in the throes of anxiety, I am caught in an awful cycle of thinking the chest tightness I always experience is putting me minutes away from a heart attack or pulmonary embolism. To know that I am completely healthy and not at all anxious about work, or social life, or really anything in general except DYING TODAY!!! is immensely frustrating.  When the symptoms aren't there (read: persistent chest tightness), I can go weeks operating normally. But then the chest pain starts again and it enhances my anxiety and I can't talk or eat or be with friends or be in public for long or engage in physical activity outside of stretching. 

I've dealt with this for years, but it peaked in July - September of last year, which got me started on my Lexapro journey. 

Does anyone have good ways to frame this in your mind or good ways to relieve that chest tightness that restarts the cycle? Otherwise I just inevitably end up in a hospital or at the doctor again (and I always get the "All clear" as a healthy 25M)
