Had stage 1b lobular breast cancer : how to stop anxiety

After 7 years, stage 1b lobular breast cancer with constant anxiety. i had bmx, radiation and anestrozole for 4 years. no chemo i constantly read google and have not found a way to calm down despite taking antidepressants and i feel upset most of the time except when i go to sleep.
