Confused and need second opinions

This will be a novel bare with me! I'm currently awaiting a solid diagnosis (yes or no) for bipolar 2. I've struggled with depression and anxiety since I was a young teen (I'm almost 26 now). Here's what got me to this situation:

5 months ago I got genetic testing done to see what antidepressants work for me. I got stuck in a bad enough depressive episode again that made me consider medication again after 5 years of raw dogging it. When I was 16-19 I tried 4 different. SSRI/SNRIs. All sucked. Didn't have a good experience on any. Fast forward this gene test, all of those are on my significant gene-drug interaction list. In fact, only 2 anti-depressants (SNRIs) are on my a-ok list.

I'm taking pristiq and had it upped to 50mg and almost exactly 3 months in I had a manic episode. Had to admit myself to the ER for what I was assuming was serotonin syndrome. Was in for 4 days, resting heart rate 130 tachycardic yadada on Ativan for 4 days.

I've never had a manic episode like that before and it was quite terrifying. I was told to get evaluated for bipolar 2, so naturally, me being me, I start researching it bc I've never thought about bipolar before. It's resonating a lot.

Saw a psych. She said I'm probably bipolar but it just needs further confirmation and she'll probably try me on a mood stabilizer. One week later I saw her again and all of a sudden she doesn't think I'm bipolar and is trying to prescribe me an SSRI, which I should not take. I'm so confused now

Has anyone had a similar experience with the whole mania thing and antidepressants? Or does any of this sound like a familiar experience for anyone? I have never been hospitalized for mania like that before or depression, but I do get bouts of clinical depression that can last up to 4 months.

Im heavily pondering the difference between hypomanic and non-depressed. The depression is easy for me to spot and define. I clearly have never been full blown manic like that before cause I simply was acting a fool and was scaring everyone around me. I have an appointment set up with a NEW psych on dec 11th but that's so far away lol
