I think I’m in love with my sister (23M 27F)

I’ll cut to the chase off personal reasons but I’ve grown close to my sister as a result off both negative experiences. I’ve been a bad brother and getting yelled at for things I’ve done wrong and these arguments resulted in me opening up to her, we’ve started to do things together as friends, and I have developed a deep appreciation for her. I’m having sexual and romantic feelings for her and I don’t know what do about it.
