Beauty, you are a strong person! You give inspiration to others. You are just having a tough time right now with the dx. It is understandable. Even though you suspected for 8 years, it is different hearing the definite! But at least now you know and you can start to improve and make yourself healthy in all the ways your body needs it. Take your time. It will come around and become second nature for you with all you need, vitamins, exercise, mental, etc.
Also remember we all care and are here for you! You are lucky to have such a supporting DH also.
