am i going to die

thanks for taking time out to reply.. i need all the support at the moment.. had an echo last week, my third one.. they shd be able to tell if there is some problem in the heart but all seems ok.. also i dont think i hv got water retnetion as i am losing weight fast and there is no bloating.. the scans dont tell if there is cancer in the lngs or infection.. and docs suggest that as long as it doesnt get worse not to take nay medication.. what do u say..remember i am on herceptin only
