I'm 21 and have been diagnosed with severe anxiety for about 3 years. Recently, I have been having small episodes where my heart rate increases and I have a tight feeling in my chest, almost like someone is stiitng on it. Last night at 2:30am I went to my local accident and emergency as the feeling was worse than usual and wouldn't go. After 4 hours they decided it was stress/anxiety and told me to go to my GP and get some medication to help slow my heart rate. I can't visit the doctor until Monday (tomorrow) but my chest is still tight, does anyone have any advice to help cope until then? Any advice would be greatly appreciated.
