I find relief in knowing this life will come to an end, and is not forever, and going by averages, I am 30, so not long left now, last night I think I had a mild heart attack, I can only sleep on my right side, when sleeping on the left side my heart keeps feling like it's stalling..so much so, I have to kep getting up and taking deep breaths, feels like my hearts stopped or something.....oh well an early death .
don't ignore it.. there is a link between depression and HRV. http://news.bbc.co.uk/1/hi/health/3543175.stm
go to your doctor and get it checked, he might perscribe more exercise or some happy pills..
