I'm grounded and don't know what to do about my parents

so im grounded. for a long time. cause im stupid and accidently left my myspace up one day and my mom found it. (im not suppost to have one but it took me 3 years to finally get caught with it) and anyways. my mother also found out that I have a girlfriend. (and im a girl) so she pretty much FLIPPED about that one. (she read my messages and stuff thats how she found out) so now im grounded for pretty much ever. no phone, no friends, no life. it sucks. they dont approve of “gay” people b.c its against our religion. so yeah. and my parents are pretty much in complete denial. they never liked the girl in the first place cause she wears a lot of black. and then they found out I was dating her so now they absolutly hate her and forbid me from ever seeing her again. and I love her. so I dont know what to do. ill still find a way to see her. but my parents dont think im gay, they just think shes is “minipulative” and she just talked me into being bi. haha they think gayness is herreditary, so I cant be gay cause there not. stupid. anyways I don’t know what to do. being grounded sucks, I want to see my girlfriend/bestfriend again cause I don’t know what ill do without her. I know they will never change there mind about her tho. and I just keep going along with there idea, and denying that im gay. cuase they would prob send me again to come christian bording school if I told them I was. they would think im the devil or somthing. HELP. I hate this. my life bassically sucks right now. ugh.
