Hello i am an 18 year old guy who recently ( about 3 weeks ago ) started heaving problems. It happened one day when i was hanging with friends and suddenly i got this pressure tense feeling in my head ( forehead and back of the head it varies from time to time ) at night i had a feeling that my vision was hurting and like going around although i wasnt moving my head and when i got up i had this total vertigo and black flash in the eyes for like a second . After this i constantly feel tired and have this heavy feeling in eyes and tense feeling in head and neck as if i didnt sleep for a year and as well i feel nervous all the time. Sometimes i get something like a fear atack when i start thinking that i would die or that i have some horrible disease. After some time and a whole load of vitamins it kinda went away but than sprang up 3 days later. I should mention that i became very irritable and that before that my life has been always very very tense. I had university exams and i have troubles in my family everyday and sometimes i really feel miserable although i feel really ashamed of myself partly because i was a nation olimpics boxing champion but it as nothing to do with my situation because i gave up the sport 2 years ago.All in all i must say that i had a really tough life and mention that there was no day in my life from the period of being 10 years old till now that i havent spent a day without being nervous. I had all tests done like CT,Neck x-ray,skull x-ray,blood test , urine test, ears eyes and throat checked andi have been to a neurologist who says im totally fine. But i really ask you to help me and dont simply reply with a message that you feel the same way because i read like a thousand of those and yet did not see an answer. Please i am feeling really desperate for help. Oh and during sleep i started heaving nightmares.
