Suggest Remedy To Regain Normal Health After Childbirth

i am 19 year old and gave birth 9 weeks ago to a gorgeous baby boy who i love to bits. i had a normal delivery but had to go to theater afterwards as my son was 9lbs 3oz and i had a third degree tear. since iv bin home i have been in and out of the hospital so many time as i have not felt well since the birth, i have expirienced chest pain and the hospital treated it as a blood clot but the scan came back clear. i have headaches and feel really dizzy and feel dreamy i also have stomach pains sometimes to. i feel so tense all the time because i just dont feel well i feel like i could collapse on the floor any minute and die and it really scares me. my gd recently diagnosded me me a slightly overactive thyroid but he said it should correct itself i have to have the tests repeated in a few weeks. please help as i am really desperate now as i have not felt well for 9 weeks i just want to feel normal again
