Its 4 in the morning and I can't sleep. Every time I try to sleep my heart starts racing and I keep getting this weird overwhelming sensation like I'm falling or something. It's so hard to explain and very frustrating. The last couple of months have been the absolute worse! I have real bad anxiety attacks which often occurs when I finally do fall asleep. I have made several trips to the e.r. bc I swear I'm having a heart attack. I have had many test done, EKG, stress test, chest x-rays, cat scan and all have cone back fine. My doctor says that its just anxiety but I just can't wrap my head around "it's just anxiety". Every tingle, sensation or pain that I feel, I swear that something serious is wrong and that I'm dying. Everyday I live in fear that I'm gonna drop dead. I've convinced myself that I have all sorts of cancers. I stay awake googling symptoms of things and if I have even one symptom of anything, I start to panic. This is consuming my everyday life and I just want to be myself again .
