Every since I lost my mother a week ago I've been stressed out & getting barley sleep & ive been having anxiety!! , I started to notice that my chest been hurting on my left side where my heart is .. kinda above my breast & under my collarbone area ' kinda feels like persure & feels like I gotta breath in & out . I seen a doctor & he told me it was anxiety!? . Has anyone else had this before? What seem to help?
