You need to see a cardiologist darling who from what you have said should put you on something like digoxin
tablets which will slow, strengthen and regulate the heart beat.
There is absolutely no need for you to be suffering like this. you could be living a perfectly normal life with the right medication.
It is nothing which can't be put right, so don't let it carry on. I honestly despair with some of these quacks who call themselves doctors!
Good luck sweetheart I hope you get it sorted quickly so you can get on with your life,
Lots of love.
