Neuro Dr didn't take me seriously because I have depression??

Hi all, I am seeking just someone to listen and also to share their experiences in being diagnosed, especially any troubles they had in the process. I'm new here and don't have an epilepsy diagnosis. I've been to the ER twice in the past three months for 3 episodes of what the ER doctors and the doctor at my University Health Services think are seizures. I had a CT scan, EKG, MRI, and bloodwork and they all came back fine, which is great! The next step was a neuro appt, which I had today. So today I had my neurology appointment, and I went in with a great attitude, sure I was going to make progress. I know they had all my files from the ER visits because the lady at check-in had them, but the doctor had reviewed none when I met her. I explained everything to her, and she reviewed my meds and saw I was on SSRIs (I have been for roughly 6 years) and immediately assumed I have anxiety. I tried explaining the meds are for Major Depressive Disorder and not anxiety, but she thinks there is just something wrong with my mood. I think she was able to write off the episodes as anxiety attacks because of the meds and because the suspected-seizures aren't the stereotypical thrashing about kind (I can't breathe, have lapses in memory, stutter for about 5 seconds beforehand and then can't move or talk at all for about 30 seconds, feel fine afterward). But all three times I had them, I was not anxious at all! I was actually feeling great and quite happy before they took place. I am so frustrated that I feel like I am not being heard. I am not a doctor and certainly do not know as much as the neuro, but I was so upset at being written off like that. I'm going for more blood tests (Lyme and something else) and also an EEG, but I think that she's prescribing those just because she feels like she has to. Also, I am 20 but did not wear makeup today so I looked about 16, and my mom drove all the way up to my university because she got protective and the doctor was much more prone to talking to her than me (my mom insisted on being in the room - guilt-tripped me when I asked her to stay in the waiting room both before and during the appointment). I think because I looked young, I was taken less seriously. I have noticed that happens to me sometimes. I am just so upset. I would so much appreciate any thoughts or stories you can share. I feel really alone because I don't want to bother people with this. Thank you.
