Hi.feeling heavy head for 24 hours.PLZZZ helppppppppp!!?

hey i am 18 years old. Male.and about the nick.Lol i didnt chose it i m with default name which remains britney whenever U choose yahoo answers with out choosing the nick. and i feel heavy head all the time. I feel like i am living in a dream world. it dont seems to be living in a life i was living 2 years before when every thing was relaxed and sleep was normal,life was happy and good and relaxed. it happened in a sudden way when i was 16 in summer when i was really happy by having being ped in the examinations(which i wasnt expecting) but as my holidays went on i planned to go have some weight lifting.At the very first day i exercised beyond normal and lifted the weight in a wrong way(well i didnt knew that time much so lifted in a odd manner life holding the weight in air for about 2 to three minutes and then with a sudden lettiing it down.i did this at the time of my extreme stamina limit.then while i come up to have a cup of tea i figured out that i m having difficulting in holding the cup and felt pain in left hand. and felt like i cant move my left hand to full extend. Well i felt happy that having exercise had some result at that night when i slept had a terrible pain in my neck shoulders. I thing its normal pain when u lift the wieght but then it continued for days then i become really tensed as my neck also was stiff and decided to visit a local doctor So my doctor told me that its nothing that too big it will just go on in a week or so and he gave me some medicine. i ate those medicine for a week but still then i cant move my left hand.So i went to specialist opto doctor who gave me medicines and told me to come in a week. So in a week or so i felt change and my arm started moving to a more extend than before but still not full recovery.After a week i went to that doctor again and told him that i feel better than before but not full recovery doctor again gave me some medicines which i took for about week or so and felt no change than before but 1 thing i felt at those interval is that the effect of my arm has started coming on my hand and i felt that my hand had started showing lower flexibility than before. So in a very sad mood next appointment i told doctor "o my god its like my hand is gonna be less flexibly than before as the time will go on. And in a lot of worry he checked my hand and arm movement and told me its look like its something very serious problem with.I m giving u those strong medicines. take it and if still it dont go u have to do a mri of spine. and then i took those medicine a a large quantity at 1 time i took about lots of type of medicine and i felt its side effect so much that i felt my mood changing and headache feeling and depression feeling dizzy etc. well i cant tell how much pain i felt by those medicine and by that interval tha whole story starts. I felt like I have heavy head, feeling like living in dream world,always showing anger and feeling frustrated,hopless,tensed like the thing called relaxation has left my life. I called the doctor and told those feeling he told me i will talk it at the next appoinment which i gave u.But as i was frustrated to hell. i never went to doctor and abondoned those medicines.then went to another doctor and told him the same story that the doctor has ruined instead of figuring a solution he should not be giving me medicine who could have a permanent side effect i m feeling now.but doctor saw my medicines and said i dont think much it is cauzed by those medicines. and he checked my spine etc and told its normal u dont have spine problem.etc he gave me medicine for hand etc. he said it will go naturally by time and that the headache may probabaly cauzed by bad eyesight. the hand went to better position to time. But i didnt felt that much change as by those before medincines it had been better.but the hand remained mostly the same especially the left hand . and i feel like stiff neck alll the time, pressure in head and like its gonna burst. i went to see eye doctor i had very little prescription. but it was in 0.25 sth.but again with gles i felt the same even for wearing it for long time. i went to neurologist then took his medicines and nothing happened he also refered me ct scan at end he said u r normal.then 2 years of 24 hours pain feeling headache in sleep etc. i went to phyrist had anxitey depression pills but again nothing happened.omg. now i m feeling like wut to do where r those good years.i just need relaxation. which i always dreamed of when wake up. But never had i feel i had sth other wrong but this thing goes.But now i feel life is waste for me. i feel memory loss. just i feel like aboslutely the same feeling like living in a dream world like not in ur senses. Not only headache i feel but i feel unconciousness like not on ur senses like living in a blurr virtual world. PLZZ help me out on this i just wrote it becuz i feel really hopeless and i feel that whoever tell me suggestion may god give him the highes
