Dear Casakelsey
1) You are NOT a failure - you have made the effort to contact your GP and started on the path to sorting out your health; it's a journey that takes time, you will get there!
2) Stress may be affecting your BP - I've always had low BP and stress hasn't affected it, but had high BP for the first time a couple of years ago while under a lot of stress. Maybe our bodies get less able to cope with stress as we get older? Anyway, my GP decided to monitor it and a few weeks later it was back to normal. I did put some effort into eating/exercise/relaxation, so as Prajna says, do look at some natural ways of dealing with it - apart from the physical benefits, it can be a real boost to feel you are doing something to help yourself!
3) Have you noticed if your heart palpitations are linked to anything in particular, eg. time, diet. I found I had almost zero tolerance to caffeine and sugar - made my heart act up so much I felt like I was going to drop dead! Cut both out completely for a while and now I can tolerate small amounts on good days, but I still have to be really careful, and I can't have tea AND a biscuit, it has to be one or the other!
Hope you get things sorted soon. Hugs x
