Hi
I also noticed that your 'Stress symptoms and consequences' nav bar was not closer to the top. Some people are actually trying to figure out if they are suffering from stress..........might be worth moving that one up? Just spotted the causes of stress in top nav bar and went to a Google Ad. That would put me off and I would move on.
I could not see your content at first glance just ads - and if I were clicking around the web I move on. Move some content up so that we see it straight away
