Not been on here for a while (been steering clear of Google) bit thought would give an update on where I am at. I went through a tough time of feeling I was going nuts, couldn't do much as very weak and generally feeling unwell. Today is a different me and fingers crossed it will continue. I've gained 2 stone, eating like a horse, sleeping a lot better and exercising every day (4-5 mile walks, joined gym etc) ... went to docs due to mental state and he spoke to my consultant and has put me on a low does of beta blockers, these may not be for everyone but they have turned me into a positive different person. I stay off Google and try and look on the good side rather than doom and gloom all the time. I know things could take a turn for the worse at any point but at the moment I feel good (and I am no longer yellow) all being well back to work in a couple of weeks and hopefully the future treats me well.
Thanks to everyone who has helped me along this rubbish journey and sure I'll be back again soon.
