sick and tired of getting my suffering undermined

I am suspecting that I have BP 2, I have already posted what suffering and everyone said that they can relate. I know its not a diagnoses but I feel relieved that its not all in my head.

I think I had an almost 3 day long hypomanic episode (not sure if its lengthy enough). But i felt very impulsive as in i have this energy that i NEED to get out of me, like its crawling out of skin. And not to mention being extremely hyper and and talkativeness.. I just talk and talk and talk (I feel like my jaw does not belong to me).. and I actually managed to finish writing a really boring tough paper. And i am surviving on an 2 hours of sleep (i woke up 8:30 yesterday and slept 6:30 today and woke up at 8:30 for school - its 4 pm right now).... I was not being myself and my friends noticed that.. thing is - 3 hours ago i just felt like my brain switched off and i felt empty.. I mean the sudden mood change made me cry because it was very.. sudden.

I got scared thinking 'oops, is this going to be like my last (episodes)?' because last time I went from being depressed for almost two weeks to being extremely hyper for 3-4 days.. since then i just had a very neutral mood (its when i feel myself the most)..

Anyway, I just ran to school clinical psychologist and she completely undermined what I am feeling, she kept on telling me things like: its in my head, i am just acting like what my friends are telling me of what they think of me and I should forget about being bipolar (and she didnt even assess me)..

I feel so bad because I always knew that there was a problem but I could not know what it is.. especially when im in distress.. I was told about possibly having bipolar by a friend who knew someone very close to her who had it and i reminded of her so much.. I know that its not a diagnoses..and i cant really get one until i visit a proper psychologist/psychiatrist until i have the money for it (i am currently saving up)..

I just want to know, if any of you have been told, or read about bipolar and felt its the only explanation of what they are feeling/going through before getting clinically diagnosed?

Yes, before my dx, I often wondered if I didn't have some type of bipolar.

....and I can relate to being dismissed. Especially by doctors.
