Two days ago i heard about kidney failure and i googled it for some stupid reason, i haven't been that anxious but i've presented with l a lot of the symptoms: weakness, dizzyness, bad nausea, confusion, finding it hard to move, feeling like i'm going to collapse etc. I've felt all these for two days, and i've just been in bed was it just the worrying and anxiety that caused it, or is there somethig wrong?
