Hi, I was wondering if anybody could give me help/advice, for the past couple of weeks my sleeping pattern has been all over the place. But the last couple of days I have really been struggling to sleep, every time I close my eyes, I can feel my heart rate increase and thoughts start racing through my head, I feel as I'm having a panic attack. I went to the doctors and he prescribed me with some beta blockers but I've had 2 today in an 8 hour window and I still cannot sleep. I'm growing really worried as I have college tomorrow and I still cannot sleep, I'm 17 years old. Sometimes I feel through the day as if I am going crazy as my mind is flooding with a traffic of thoughts.. Has anybody got any advice?
