what should a nutritionist do for me?

i have my first consult appt with a nutritionist at kaiser tomorrow. what should i expect from this appt? can a nutritionist even help me figure out what i should be eating? i am very knowledgeable in health/fitness/nutrition and feel like i will know more than the person i am going to meet tomorrow since they are not a registered dietition. i want to see someone who can tell me what to eat to help alleviate symptoms from my medical conditions as well as lose the weight that i've put on since becoming hypothyroid. i am hypothyroid with hashimotos disease (currently experiencing very bad symptoms of fatigue/memory/low body temp/chills/bloating/water retention/swelling and inflammation). i have ibs/gastro probs, anxiety/panic/depression, asthma and mild eczema (hands). any thoughts?
