i am not a doctor, but it's obvious there is something bothering you. the truth is the doctors don't always know. they can't tell you, "i don't know". how stupid will they look. some are really lazy. what do you mean by perceiving everything differently? visually, things look different. blurred vision, hallucinations? what ppl say? what do you mean by chest pains and heart pains? how often, when, are they like stabbing or burning. does it hurt to breath. do you have unexplained weightloss/ weightgains. think of all ur symptoms. do u get cramps. how is the skin on ur face: dry, red? when u say problem with concentration how so; listening, looking, u stare blankly to places, forgetful. do you feel at all fatigued? do u shake?
go and c another gp. just tell them ur symptoms and c wat they say. coz listen, doctors can falsely prescribe, kill ppl from stupidity. you need a good lawyer and a good doctor. they can make a bigggggggg difference. try and get a doctor that is recommended. this man said, he was having pains in his chest. he went to his doctor, he said something to him like ahhh no problem ur healthy. you just need to relax. go home have a glass of grappa or wine tonight. u know what, and he had a heart attack the next day. he used to go to that doctor for 20 yrs. he goes to a doctor now and demands what he wants done.
if there is a problem. believe me. u r not imagining it. there must be a legitimate solution, that will work for you.
i'm thinking, dont just let it go.
your next step is: go to a naturopath..... yes, look one up. and go. ask them to do a complete analysis. they will recommend/ refer u to a good doctor.
u do have a reason to b concerned, do not let anyone tell u different.
go to medicinenet, read different material.
would u consider yourself to lack motivation... could u maybe be depressed... ? it's good to consider all your symptoms.
for u important: make a plausible sleeping routine. possible u have difficulty sleeping.
there is a solution.
