I didn't sleep a wink last night. I was exhausted when I went to bed and felt fine but moments after I lay down I got that weird feeling in my heart and then it started. My heart was doing backflips and frontflips and then racing. It felt like my whole body was shaking. Everytime I nearly dropped off it was like my heart had stopped and I gasped for breath. I honestly think it's just going to give out! The strange thing was I was too tired to actually go into a full blown panic attack. I'm feeling so tired this morning but I've got that feeling in my chest that it could start again any moment. I'm just exhausted with it all quite honestly.
