You need a very big Grandpa hug a verry big one and all the comfort and "love" I can give you.
If you have got the diagnose Bipolar Disorder, then there is only one thing that works....treatment.
I am fully aware that you will "suffer" more from the medicine and that some of the bi effect might be not that favourable, but if you don't take them you will be more and more eaten by the illness until you have no control over yourself and your actions.
You need to take contact with all that can help you....you need to put your life into regularity.....you need to have much training....relaxation...regular sleep and so on.
You must be open to try out different kind of medicine and try to approach this illness with what you can manage of positivity and fighting spirit.
There is a lot of people who get it...and many people have lived with it in an almost normal life situation.
The hard part is to admit that you need the treatment and work with the helpers and not against them.
I include a link to a forum which can give support and where you can read about it.

I give you all my best wishes, I even have tears for you.....must you get the power to fight it!
