Nausea in the morning?

Well I have been having very bad health anxiety and fear of having a serious heart arrythimia that will kill me. It has mostly just been heart palpitations and weird feeling in throat, especially when walking and I feel like I can't breath. But the last few morning I have been waking up a nauseous feeling in my throat. Of course nausea has to be a sign for cardiac arrest which is why I am slightly worried. Is this a typical sign anxiety. Please help thank you

It is definitely a sign of anxiety.. I was nauseous everyday for about 2 months and I still get nauseous but it was so bad to the point I didn't want to eat my food because I was afraid I was going to throw it up. So I really think it's just your anxiety 

I'm going on day 3 of constant anxiety and several attacks and these are absolutely signs of anxiety. My throat hurts, my ears ache, my heart flutters, nauseas and have to force myself to eat, tightness in chest, feeling as though my body is "buzzing", hot flashes... just to name a few. You're not alone.
