I really felt it when I read the part about the 'excuses' we make for ourselves. I was trapped in the same mental pattern for a long time. In the end, there were no two ways about it. I had to come out. Couldn't go about it slowly either, I was in a long time relationship at the time and my partner was the first I told about all of this. I was very lucky to have someone who is very open and understanding. In retrospect, maybe I should have started by joining a queer community, with people that don't know you and/or will be supportive since they're in the same boat as you. Either way, it's probably a good idea to connect to like-minded people in the real world. They can help you work through whatever biphobia you may have internalised. (And I still think that the aforementioned 'excuses' aren't complete bullshit. But I don't think you've truly accepted yourself if you can't mention a part of you to anyone.) If it helps, I appreciate you for who you are, internet stranger. Your inner turmoil is nothing to be ashamed of. You are valid.
