Short term memory is going fast. I hurt all the time in winter months I bounce and shake so bad I need a cane or walker. In summer I feel like my insides are a raging inferno and I have to be iced down. And they get mad and frustrated cuz I caint remember what I did or said five min before. my doc said I can not work . I also server epilepsy. Raynaud's desiese. Sever high blood pressure brain shocks. And I already have had strokes I feel so guilty ashamed and I'll don't know how to make them understand I'm not faking. Help
