"I thought I was having a heart attack"

So, this afternoon I had some chest pain, coupled with coughing blood a few days earlier, I'm not registered with a GP, and I have no idea what do do. I called for an ambulance, they did do all the checks necessary, they were very helpful, very efficient, but above all, they were the least "we'll just do this and leave", they genuinely wanted to check on you and make sure that everything is actually fine. I ended up in the hospital where they took a blood sample, ran some tests, it took a while, but after all, I'd say I was very satisfied with the staff members. The GP they appointed for me actually tried to explain why I was having pain, they were genuinely caring. So, I'd like to applaud them for what they've done.
