My mom is controlling me, what should I do?

I'm 13 years old now and presumably I can take care of myself and have my own ideas. My mom on the other hand is always trying to control me, mostly with her obsession of her new "boyfriend", and the desire and need of me to bond with this man. It all started when my father died of cancer, about 8 months ago. Only 3 months later after his death, she gets a "boyfriend", which turns out to be my biological father through a DNA test. Not only am I still coping with my father's death, I am literally being pressured to "bond" with this man, who is technically my biological father, against my will. I have no idea who this man is, and all of a sudden this man is my father, and I am supposed to "bond" with him and I am supposed to accept him as a father figure in my life. Truthfully, I hate this man. I want nothing to do with him and his drunken family. I have told my mom this, and she said she doesn't care, because no matter what I say or think, they will still be together. She has, over the 5 months that he has been in her life, forced me to bond with him against my will. I told her that no matter what she says or does to me, this man will never replace my father who has raised me since birth and accepted me as his own. I will refuse to bond with that man, and subsequently, I get something taken away (Cell phone, computer, etc..) and not being able to see my only friend that I have, and still be forced to bond with this man. Now, she has booked a cabin in another state over spring break for a week, and she is forcing me to go to with him and his drunken family. She said I don't have a choice because this will be a "Bonding experience", and if I like it or not, I'm going. I don't trust that man either. Something about him isn't right, and I can sense that. Please, can anyone help me? What should I do? What should I say? I know I need to stand up for myself, but I can't. She is so controlling and manipulative. For example: When I ask her if I can go to the movies or do something with my only friend during the weekend, she says "I don't think so. Unless you be around him, then maybe I'll think about it".. I don't know what to do. I need help about what to say or what to do. I am at my wit's end, and I can't take this anymore. I need help, ASAP.
