Hiding my feelings Because my parents disapprove of me being lesbian.

My parents bug me about being lesbian because I Hang out with this girl to much I can't lie...It is true. I have to lie though because I would get kicked out and they probably would not support me anymore. I know my sister does not have a problem but they want me to stop being friends with her. I'm in college...about to graduate and I love her but I can't be open because I still can't be independent and hoping to countinue my education but it's so hard to live at home when you have to hide yourself . She loves me so much and if they saw how she treats me and not what her gender is ...I knew they would understand. I can't move out soon but it's just so hard. Anyone else going though this ?
