psychiatry appt - feeling nervous

i have a psychiatrist appointment to discuss adhd tomorrow and im nervous af. the last psych i spoke to said he wasn't sure about adhd as he wanted me to get on top of my anxiety and depression first so my symptoms for adhd were clearer and diagnosed me with bipolar 2 even though i felt most of my anxiety and depression stemmed from adhd symptoms. he did prescribe me catapres to hopefully help with some of the adhd symptoms before digging deeper in to it. im just nervous im going to pay another $900 for someone to tell me the same thing, im tired of my feelings being disregarded and i find it hard to advocate for myself. ive printed off 4 pages of symptoms with examples and how its affecting my day to day life so i dont forget to mention things as i tend to downplay or forget things when put on the spot. im just feeling so scattered and nervous, but hopeful this new psychiatrist will listen to me. i guess this more of a vent post - thanks for reading. wish me luck!
