So lost right now and so afraid

This is really going to be hard for me because I'm having to move back into my foster families home because the place I'm graduating is giving me barely any money to get a place to live on my own.
Also I am a lesbian I have had to hide it since I was fourteen because my real mom has liver failure and a blood disorder and I was the only one out of my family that stayed and help her. I gave up my childhood and teens because I didn't want to let my mother die. I got job and paid the bills and slept in the kitchen so I would be closer to her when she needed things during the night. I Lost all my friends did terrible in high school and was disown by my family.
Then I meet this guy and I thought I had to make it work even though I don't like guys. At first he was nice then 3 months into the relationship he started raping me and yes I got pregnant I hide it well until one night he found out he punched me several times in the stomach and I lost the kid 2 weeks later. finally when I got enough courage I told my family and him that I couldn't take it anymore and I got treatment for cutting. Three days into staying in a new town and at this treatment place. my mother called and told me she hoped I had a good life and that I didn't have a place in her life anymore.
Then a Christian family took me in and they don't like gay or lesbian people I came out to them about being bi but they told me I was bi because of the way men treated me so I never told them that I was a lesbian.
Came to a place people don't judge people for liking the same sex.
