Welcome to PC ..

You will find tons of information and first hand stuff around here .. we all have " stories" of our own unique Bipolar ..

First off dont panic .. You have probably been bipolar for a while and you muddled along so really not much has changed except now you may get a " label"

There is no logic when it comes to bipolar .. There are many things you can do to help yourself stay stable but sometimes bipolar just bites you in the as.s.

Talk therapy can be very helpful believe it or not .. It helps me stay grounded when if not for my T ( therapist) I would be floating off like a mad balloon or sinking into hell.

Things that can help you.

Having a regular sleep schedule is so helpful.
Exercise
Eating healthy
Meditation
Yoga
Mindfulness
Breathing exercises

just to list a few

Again welcome to PC hope your able to find support here like I have
