hi , first of all i sugest you to start anti hypertensive treatment including diet control ,regular exercise , morning brisk walk , weight reduction and drugs. ignored high bp can lead to several complication including kidney failure and even heart failure so start its treatment immediately.now you should also go for ECG and echocardiography, chest Xray and chest examination by a physician. your breathing difficulty can be due to pulmonary edema due to untreated high BP or other cause which will be revealed by chest x ray and if needed then go for pulmonary function test also. discard alcohol immediately and adopt some other measure for stress releaving like yoga and meditation. thanks and take care.
