How do i deal with my mother?

I need some advice. She's one of them parents that will not let me come out because she feels it's not necessary to tell everyone about my gender/sexuality even though its really getting to me. She blamed me when I got bullied as I was out as lesbian and she said that I was digging my own grave. This was when self harm, low self esteem etc began. So she took me to CAMHS which offered counselling every two weeks and the woman I saw was amazing and accepting helping me deal with my problems. Yesterday I told her I was watching the fosters:
Me: So mum I'm watching this program called the fosters.
Mum: Ah so it's where the man and woman foster kids?
Me: Yeah..but it's a different type of couple.
Mum: Like a gay couple?
Me: Yeah it is, a lesbian couple they are the main characters
Mum: (a bit akward and disgusted) Do they do stuff?
Me: Yeah but the straight people do it more
Mum: I don't think it's appropriate for you to be watching, puts stuff like that in your head.

I was just hurt I was suffocated, the fosters and modern family is a form of escapism for me as I'm not allowed to come out and plus I'm out to her as lesbian. She's banned me from watching them. I just went upstairs and cried. I had flash backs when she said she'll never accept my girlfriend and if I'm trans* she'll never let me transition while I'm in her house. But she said that she'll accept me no matter what, but what type of acceptance is this? :bang: :help:
We where watching and Indian channel where transgender&intersex people where being mistreated and forced into drugs etc and I burst out crying. I was surprised that they where trying to stop the oppression against hijra's (intersex) people which made me really happy. Especially in a country where homosexuality is strongly opposed.
