Hbb symptoms and conditions

I am a 35 year old woman and my doctor put me on lisinopril 10 mg at first I had the cough that I see almost everyone gets,but I could deal with that then I started getting very tired all the time,I had started working out and was feeling better since I had been diagnosed with hbp,I ws following the dash diet ,it is said to be real good for hbp.I started taking lisinopril in may and by November I was a complete mess, My doctor never told me of any side effects so I read the little paper that the drug store give you on the side effects but it does not do this justice!I was so weak and tired I could not get out of bed,On thanksgiving I went to the hospital and told them I have no energy I feel sick all the time and dizzy,of course they sent me home thinking I was insane because I was crying ,I felt depressed all the time I did not know what was going on .About two weeks later very close to Christmas I started having palpitations at first I just thought it was stress from the holiday then they came more often ,I was so scared I went to my doc. told her I was have palpitations and she blamed it on my weight! ok now I am overweight but I have lost almost forty pounds and was walking four days a week ,then I said to her do you think it could be the lisinopril ,then she said something I will never forget she said well who put you on lisinopril? I was done then I said well you put me on the drug ,her face went white she said oh yes you should stop taking it I will give you a different one ,so I went home and took it for week and the palpitations kept getting worse so I went back to her and told her I was still having palpitations so then she gave me an e.k.g. and found nothing of course.I told her I was going to stop taking the meds all together and she then said she wanted to see me in two weeks ,In the meantime my boyfriend made an appointment for me to see a heart doc. ,he took another e.k.g.(did I mention I have no insurance)and said there was nothing he could do that I need an echo and a holter moniter for 24 hours to tell him whats going on .I had been off work for a month now so I had no money left so I started crying but my boyfriend paid for the tests to be done which cost a pretty penny .I am still waiting for the results of those tests yet but the more I think about it the more I wonder if I was having lisinopril panic attacks?I have stopped taking all blood pressure meds and my bp is most of the time 120/80 sometimes it is lower sometimes it is higher but I would rather not deal with the side effects of the drug until I really need them!
