Welcome to health care magic
I can understand your situation. I appreciate your effort to seek online support.
You are suffering from " Secondary Amenorrhea". First thing you have to do is to visit a gynaecologist for detailed work up. Associated dizziness
, soreness of breasts, cramping etc points towards some gynaecological pathology.
However, it can be due to associated stress and anxiety symptoms. For that, consult a psychiatrist
for some medication like antidepressants/antianxiety drugs, psychotherapy
and relaxation techniques
Hope it helps
