What is my problem. Is it all anxiety?

Hi Doctors, I am a 26 yr old guy who recently had an issue that my hands were shaking. I went to hospital & there they took my ECG, 2D Echocardiogram and Trop-I test. All of them came normal and Doctor told me that its Anxiety related. This was 2 weeks back. I was fine later. Day before yesterday I had an issue that my Chest pained so I informed Doctor again and he suggested that its all Anxiety.  As happened at night, I wasn't able to sleep properly as I was worrying and had went to hospital in morning then Office. Yesterday night, I slept but I had to wake up early due to work. When felt dozy then went to sleep as my work completed till Afternoon after which I had headache but went to Office. Now while trying to sleep today night, I got a feeling that my breathing is not proper and I cleared nose but I occasionally feel that my breath is not proper and I feel some shaking, feeling scared and that all of a sudden lost control in hand but when I try to move I can. So is it all Anxiety?
