Hello im 17 i was robbed a year ago and being having panic and anxiety for the pass few months which ked me to fear death ive been to the doctor everything is normal but i feel like im going to die soon is this a symptom of anxiety or ptsd?

It is likely anxiety/panic in the context of PTSD and counseling will be needed early before the above mentioned symptoms will start interfering with your activities of daily living.

It is not feasible to provide a meaningful opinion without taking additional history, physical examination and may be some tests. It would be prudent to see your doctor and discuss if you may be depressed. Counter-intuitive as it may seem, exercise may help. Start with low intensity exercise such as walking and gradually increase the intensity as tolerated. Drink more water. Wish you good health!
