Dear Jasper, As a colleague suggested below,assuming diagnosis is only going to make it worse.Please avoid going online for diagnosis,but of course can use it to seek advice,support. Bipolar is a medical diagnosis and is treatable. Of course your mother being a psychiatrist may be a bit of disadvantage for you in seeking correct help.If you share good relationship with her,discuss your concerns,ask her to speak to one of her colleagues to see you. Do you exercise regularly,engage in activity that differs from your routine? Good luck

Hullo Jasper, I suggest you see a psychiatrist for further clarification. The information you have given is insufficient to make any diagnosis. Best wishes
