Please do go for a checkup ASAP. It could save your life. I have had a triple bypass three years ago. I had shortness of breath for quite sometime. My energy level was very low.. I never dreamed that I had blockages consequently, I have heart disease. Stress, is a killer. My husband, daughter, son-in-law all passed away within two years, even my beautiful cat had to be put to sleep. In between all these loses, a triple bypass was done . I wish you well, safe journey. Put yourself FIRST,
