I have MS, diabetes insipidus, LBB with angina, COPD, pernicious anemia, plus depression and arthritis. After returning from a long driving trip to Palm Springs to meet with friends, where I was too beat to participate in. Plus it was 108-112. I arrived home to rest and recover, but woke up yesterday with an incredible feeling of dread and almost despair. I was crying for no discernible reason. I can t quite shake the feeling. I was also dizzy and felt like I couldn t breath very well. I have coped with these various diseases for several years and generally maintain a pretty positive attitude. This was a feeling that washed over me. Course with what has happened last night, it feels trivial, but it scared me.
