Totally new to this, had a health scare 15 months ago after breast mammogram, had enlarged lymph nodes and lump, but all came back clear thank god but since then I have been totally engrossed with worry about cancer and dying. I am 53 years old. I went to doctor two days ago after having been there for 18 months and she prescribed Lexipro 10 mg. I have not been on meds before. I have now become obsessed with weight and see that I am losing weight for no reason. I eat ok. Anyone experience anything similar.
