I Am Extremely Exhausted All The Time. I'm 41, Having

I am extremely exhausted all the time. I'm 41, having extremely heavy menstruaatiol, waiting for dr results on pap, ultra sound and lots of blood tests. I know my body doesn't absorb folic acid, I have pernicious anemia and have had 4 miscarriages where I was told I have APS, an autoimmune clotting disorder. My son was 8 weeks early, I had preeclampsia and a placental abrupt ion Nd 3 c-sections.
. My heartrate skyrockets when I walk up the stairs and my body feels exhausted all the time. I'm not overweight. I do have depression. No one ever put it all together for me. I want a life. Thoughts.
