something really triggered my anxiety so from few days i am having this fast heartbeat rate which is like my heart is trembling. and difficulty breathing also when i stand up from sitting or lying position i have total darkness before eyes and feel like fainting

While these can certainly be A/P symptoms...I agree with D.S. that you should be checked out medically to be safe.

Use your coping skills as well during this time.
