I am a 61 year old woman who has been a full-time caregiver for the last 5 years for my husband who had a massive stoke. In the last week or so, I can t sleep no matter what I do. When I go to bed my heart starts beating very fast. I have taken my B/P all of these nights and it s always normal. I am not eating as much also. I had a rare tumor removed from my neck in Dec. and really have not felt good since. It was not cancer. I don t know, could this all be stress or should I see my PCP???
