Your complaints are completely normal for your age, more than for your disease. I have a female cousin that was a low profile model, she try to go big to a national level but never achived that goal. But she always told the stories of how stressful and difficult was to meet the standards needed. How many 24 year old girls where considered themselves useless for their age and how difficult for them was sometimes to obtain a simple contract since there were many younger girls compiting for the same work. So i think it is normal on that kind of media to feel stressed.
It seems that your bipolar disoirder is quite controlled by the moment. But you should realize that you may need a drug treatment at some point and be prepared to accept it if your disease progresses.
There are multiple schools of psychiatry not just the traditional psychoanlist. Also you could try something simpler like conductual cognitive treatment. But be aware, if your diagnosis is correct sooner or later you will end needing a drug theraphy.
