Hi @Me_again,
Welcome to the forums! I'm really glad your psychiatrist referred you here - it is a great community with people that can support you from both a lived experience place and a caring and supportive place.
A close family member of mine was diagnosed with bipolar I several years ago. I remember it took him a while to accept and process his diagnosis. I think what helped him was time, support from professionals and family and friends, and finding support from others diagnosed with bipolar. I also think being kind to yourself and allowing yourself time to process your thoughts and feelings is important.
Here is a link to some information about bipolar https://www.sane.org/spotlight-on/bipolar which may be helpful to you.
For future reference if you want to tag someone so that they get a notification from you just put the @ symbol followed by their name with no spaces and then click on their name in the drop down box that appears. You will get the hang of it pretty quickly.
Take care and please let us know how you are getting on.
Best wishes,
FloatingFeather
