Coming off propanalol has given me severe anxiety!!please help

Hi all …2 years ago i got sick with an over active thyroid which caused scary issues with my heart and blood pressure..i went on propanalol to treat this and it worked well ..i have in the last 4 months gradually stopped taking propanalol as my thyroid has stabilised, however coming off the tablets has given me anxiety like I have never felt..I have learnt to deal with it and can have a good couple.of weeks where my blood pressure is stable and I feel good getting fitter …then my heart with skip a beat or something and it sets off my anxiety and my blood pressure goes high and I feel.like have gone backwards for days. its causes me to become depressed..anyone else had this …thanks in advance
