Chances are you had Bipolar before you got the diagnosis. Who knows what knocked you off track and now your dealing with the muddy mess of Bipolar ... Try not to feel shame in this, I think you will find out on your own that Bipolar is just a part of you.
Finding a good Therapist will help you learn coping skills and help you move past the scarey feelings you have right now. You will indeed feel great again. Bipolar will not always play front and center of your daily life. Just takes time to find the right tools to even you out emotionally.
Theres nothing you could tell any of us that we havent lived through or heard before.
Welcome to PC I hope your able to find the support here to help you come to terms with Bipolar
