I come from a religious family who don't believe in sex before marriage or dating outside the race and religion. I have never been very religious and have secretly dated in the past. 
I have been with my current boyfriend for 5 month we both make an effort to see each other as much as we can since my dad only really lets me leave the house for work . It helps because my boyfriends works with me. My sister is very much like my parent when it comes to  religion and values. 
When I was at work my sister went through my whole room found some journal i forgot about that had passwords written on it. She logged in to my MacBook with that and read all the iMessages that got sent from my phone to my Mac. These were private conversations between my boyfriend and I felt extremely violated. She confronted me when I got home and said she won't tell my parents about it If I quit my job and stayed home instead because I'm obviously not with the right company. She also threatened to tell my parents that I have sex and I drink if I don't do this. I'am genuinely scared of my life if my dad finds out considering she is also holding screenshots of my conversations as blackmail. 
I need my job to pay for my school, car and phone. And not to mention I absolutely love my job. I honestly have no idea what I should do anymore. My best friend and boyfriend are both offering to take me in  but my sister already warned that if I try to leave my weak mother will have a heart attack and that's on me. 

I feel incredibly guilty for even thinking about leaving my family and embarrassing and hurting their reputation. But at the same time I wanna be able to keep my job and date who I want. Only thing stopping me from leaving is the incredible amount of guilt. My sister also mentions that I'm just a dumb slut who wants sex and doesn't think about how I will be hurting the rest of the family.

I'm completely lost and any help would be appreciated please
