Why do I love her so much ?

Hi my name is Lisa Rogers, I'm 16 years old , and I'm .... lesbian . My mom Kaci Rogers sadly doesn't support me , my dad on the other hand supports me alot and is happy for me .I have a brother that is straight but supports me his name is Justin Rogers he is 20 years old and has a girlfriend and her name is Emily lovelock she is 19 years old . She supports me to and I was shocked when I found out she was pregnant with twins. They have been keeping it secret for 3 months and we found out a week ago.
