Bipolar can be hard to dx in teens, as there are a lot of hormones they are dealing with too. Only once hormones can be ruled out, can a pdoc really analyse the patient.
I think seeing a T would definitely be very beneficial to you, as you get to know yourself as an adolescent. A T will also be able to help you work out if it is necessary to introduce meds.
I hope you find some relief soon - we all deserve to be happy.
