Hi, I Had Partial Thyroid Removed Jan2017 Due To "nodules"

Hi, I had partial thyroid removed jan2017 due to "nodules" that wee not cancerous but one day "might have been".. everything about me has changed since the surgery and not for the better! I was always on adderall for years but switched to focalin right before my surgery because at the time I felt it worked better with me!! now the past 4 or so months everything is so unorganized in my life! I feel like it wasnt so unorganized definitely before surgery and when i was on adderall i feel like i was more accomplished... I am 36 year old female and sigle mom to a 5 yr old and I just want to be myself again..I go see my dr next week but I dont know what to say or what im trying to say? So with all I just said which medicine do you think will actually work with my ADD,,help!
