Feeling more bipolar but still

Hey beautiful people! 
I need your help knowing what I suffer from so I can find solutions and my psychiatrist doesn’t want to diagnose me ( just depression, no shit I thought It is diabetes) 
Let me begin with the severe mood swings! Like in a matter of seconds my mood changes but not for so long (both sadness and happiness)!

There is also this remarkable weeks of mani and wanting to do everything, and actually feeling like a god having a solution for everything! An the other way weeks of depression ( sometime severe « please stop it «  depression) 

One other factor as a social worker in a school here in France working with the kids and their teachers, I work like normally and do my best! There are some mood swings while working but I control them alongside the stress of this job! 

Studies: ah studies, there where the depression hits, like not motivation, hating the theoretical courses and don’t get me started with concentration, 0 my friend 0! This illness of concentration followed me in life too! Been months playing chess no concrete progress because of stupid mistakes! My passion of reading also gets destroyed by this!

Overall I don’t know! I feel bipolar ( or the beginning of it) especially that I feel like deeply the trouble of Anne Hathaway in that episode of modern love!  
But online tests and articles sometimes say bpd or ptsd or adhd! I really feel lost...

Thanks for your help 
Good day!
