I'm 33 years old, and only now I am beginning to notice how differently I think form normal people. If I look back the evidence is blatent but never acknowledged it before.

Simply speaking my symptoms range but essentially I have manic episodes. I can wake up happy with no reason, I can also be extremely depressed for no reason. 

I find it very difficult to concentrate, can be very impulsive, have lost weight due to a loss of appetite, and generally do not enjoy eating. I spend money impulsively and have always struggled to budget. I use to smoke a pack of cigs a day however I managed to switch to vaping. 

I smoke cannabis daily, vaping it mostly. However I rarely drink alcohol or take any other illicit substance. I get mood swings to where I can verbally raise my voice to an uncalled for volume for minor things, very irritable and generally in a state of depersonalization where everything kind of feels like a dream. I have developed anxiety towards social situations and currently unemployed due to these symptoms.

This all became apparent with major traumatic events in my life over the last 4 years.

What can I expect from a doctor if I see them?

Thanks in advance...
