Is this anemia or anxiety?

[pinkiepiepink]

I am 21 5'4 slightly overweight 148lbs. I have been to the Dr.s a lot in and out of the hospital I went to multiple care providers. I have symptoms of leukocytes in urine and no nitrates but some say I have a UTI some said no you don't stop taking the antibiotics. I have been fainting and feeling weak and tired. I have lower back pain on my left side. I bruise easily. Pale skin.Heart beating out of my chest bpm 121 usually before I feel like I'm going to faint or feel very weak with mild chest pain sometimes shortness of breath and sweating, chills inside. I have had two miscarriages back to back and found I had fluid in my falopian tube (I don't know if this is relevant) I constantly feel cold. Mild nausea. I have constipation and a history of digestion issues. wooshing noise in my ears. I finally got results from my blood tests I have a low blood count 135 ( I am not on any blood thinners) and vitamin d and alkaline phosphate deficiency's. Most doctors are quick to say that I have an anxiety issue. I've never had any feelings like these in the past.
Family history my mother has arrhythmia, and  anemia.
My grandfather, grandmothers, aunt has/had diabetes type 2
grandmother and great grandfather cancer
grandfather and grandmother have had heart attacks in their 60s in otherwise good health

Is this just anxiety? anemia?
