Headache for last 7 weeks and still going...dizziness..etc

hi, lets me start from what happend. i am 22 yrs old and i am a student. just over 7 weeks ago i was with my mates and decided to smoke some weed, i hadnt smoked some for 4 months. well anyways 30 mins into the smoke i started feeling weird so thougt might need some fresh air and with mates started going to the shops. half way my heart started pumping really fast and i really thought i was going to die that night, but later on found out it was a panic attack.

well after calming down after few hours still felt high i thought i would sleep it off. when i woke up in morning i had a headache and still high and didnt really know where i was. started getting blurry vision and started panicking. i had another panic attack and went into the emergency room. was told that its probly just a viral infection.

i then became really scared and wasnt able to have good night sleeps. i was then admitted into hospital and thats the only time i had proper sleep and felt relaxed and better. i was told that i have acute anxiety disorder but dont really know why. didnt really have a reason to be depressed.

well weeks went by and everyday i had a headache which wouldnt go away along with me bieng dizzy and light headed and many times didnt really think i was awake and thought everything is unreal. its like im high again, its hard to explain.

during this time went to docs many times and kept getting medication witch really didnt work. 7 weeks on i still have a headache but its a strange feeling..its a lil pain in the back of head and ma forhead has alot of pressure. i just want it all to go away. i still keep thinking this is not real and have balance issues at times. i just want to know whats wrong with me. the docs keep treating me as i am a depressed patient, but i think i wasnt depressed before but because everyone kept saying i was and this headache wouldnt go away i am

my current symptoms are:

dizziness
blurred vision
headache
dry mouth ( and when i drink water its makes it more dry)
weird taste back of throat
sore throat
head feels strange like this isnt real.
sleeping problems


medicataion i have been given is amitriptyline but took it 2 times and it made my headache worst and had really really bad side effects and now i am too scared to take them.

i just want to get better now and have this obsession of wanting to stay in hospital again, but dont think anyone will let me. do people think i can be admitted into hospital again?

thanks
