I need my loved ones!

my mother is mad at me because she found out me and my boyfriend that I been going out with for a year and 2weeks were having sex. its a long story but she’s more hurt then upset and I feel really bad to see my mom hurt. I was trying to get away from home but I konw that won’t work, I just felt that I ruined her life and said to me she felt like a failure as a mother and saying all types of stuff. she’s also making me feel bad by saying unnessary stuff. she’s been very depressed over me. but I told her sorry and I really am sorry. my mom the type of woman that holds grudges and I wish I can make her stop being mad at me. I know it was wrong to do at a young age and I admit I was wrong…but I just want my mom back and she also told me I gotta do a lot to win her trust back. now my boyfriend’s parents don’t like me but I care less about that I just wanna keep my boyfriend because I still love him and he stills love me. my mom tells me he’s gonna leave me one day because all guys do so I lost my virginity for no reason. but I didnt because my first time meant a lot. but anyways my question is…

what should I do to get my mother to not stress over my mistakes and be mad? and to keep my boyfriend without any problems?
