A lot going on: There's really too many symptoms there to try to address over the internet. No one disease can tie all all those things together. You really need a comprehensive evaluation that looks at your total health picture. That's would best be accomplished in a doctor's office with a person you know, trust, and like over the course of many visits. Please do consider this.
