For some people its hard to wrap there head around having Bipolar .. I was 43 !!! But it took me all of about 1 mins to say ,,, Oooooooooooooooooooo that explains A LOT !
I honestly didn't struggle with it. I didnt see the reason too. I can't change the past. But ...... I can change the future and how I want to live my life.
Maybe try and step back and just think of the symptoms you have and just focus on treating "them" ad not the scarey " bipolar" ... Because really that is what Bipolar boils down to .. treating symptoms..
Do you have a therapist? If not ... find one asap... often it helps to be able to process it with someone that can help you look at things from different angles.
Be kind to yourself
