Common Variable Immunodeficiency Support Group
Common variable immunodeficiency (CVID) is a group of 20-30 primary immunodeficiencies (PIDs) which have a common set of symptoms but with different underlying causes. CVID's underlying causes are different, but the result of these are that the body doesn't produce sufficient antibodies in response to exposure to pathogens.
What caught my eye about your post was CVID. I myself suffer from CVID, and I do not come across many people that do. I understand your fatigue. I myself suffer from fatigue. I take Ritalin, which is similar to Vyvamce. I sometimes get too caught up in my own thoughts when Itake Ritalin. I believe maybe you might be experiencing similar effects. Maybe you might be overthinking. Hope it gets better.
