"My mum's treatment"

Very disgusted with the level of care. Came in with heart issues. Chest pains. Leaking heart valve. Made to wait 7 hours before we left as mum could not wait any longer. Told patients are seen in order of arrival in emergency department, not in order of issue. She is in so much pain, but has decided to take double her medication to get the heart symptoms under control, she is on strong heart medication and beta blockers, but as she is not seen within the reasonable time, they gave us 4-5 hours, she has no choice but to put her life at risk as sitting in a plastic chair all right is making everything worse. But they don't seem to care. In my view, they are just forcing us to go through the pain so they justify making NHS  private. Disgusting.
