Sexuality crisis

Hi, I'm Hannah

I never thought anything of my sexuality until this year, when I started liking a good girlfriend of mine. After two weeks or so, I came to her and said: "I like a girl", and she was like: "That's great! Who is it?". I knew she would ask, but I never really thought of a good lie to tell:) so I was just like: "...it's you...". She was totally cool and told me it was really brave of me to tell her.
After all of this, I thought "I'm bi" because I had been with a guy and I have had crushes on guys. But I didn't take in that I didn't care when a guy turned me down, that I wanted to break up with that one guy the first day I was with him (can you still follow it?) and that most of my guy-crushes were fictional characters.
I realized I might not be bi, but I had already told my parents and a few friends I was (they were all totally fine by the way). It kind of hurts every time I think about it because I want things to be clear for me. I want to know what I am and just get this over with. All I know for now is that I'm either bi or gay (yes I know there are more sexualities but I've researched them and I'm pretty sure I'm not anything else) and that I'm obviously not alone.

If you're confused too, don't worry about it. You'll figure it out.
Love is love.
