WITHDRAWAL OFF OF TOPROL XL

Yes I have been off toprol XL now for 3 weeks and its been a living nightmare for me the only reason I keep waiting to feel better or even walk again is because the medicine I believe was killing me, I have had every side effect and them some that has been listed on this site, they misdiagnosed me and overdosed me.. I am need help if anyone here has gotten off this miserable drug after being on it for a at least some period of time and can tell me how long it toke to feel normal again please write me back on this board,,,, I am desperate been to two cardiologists and the ER 4 times in these last 3 weeks and I just want this all to be over... sorry I sound so angry but I am just tired of suffering. Thanks so much
