Severely overprotective dad. Effects?

My life has been very bleak, although I do greatly appreciate being alive,and being at school, the opportunity to see people my age and converse with friends. Yet, my dad doesn't see my way. I understand that he is protective to protect me from bad people, because my siblings threw their lives away when he was lenient with them. With me there's no leniency. I can't have friends. Period. He says that having friends leads to boys. Obviously he's been dragged into the stereotypical outlook on teens. Peer pressure. He thinks that having friends will only lead to , drugs and other things. The only friends I've had in my life that could physically be here with me and have fun with, were my niece and her sister. But her mom was having a dispute with my dad so I never see them anymore. I'm not allowed to talk to my friends over the Internet, I used to secretly, but he found out and he can somehow see whether I've been on Facebook or not. I don't get out at all. Except for groceries. I have to do the shopping since my mom left a month after my dad's stroke. So I have to take care of him, i.e get his food, pills, groceries, and laundry. And of course, I do the cleaning. I feel greatly underappreciated, because he often yells at me for minor mistakes. So basically I've only been out of the house for school, and I used to go out with my sister but she doesn't come around anymore because of my dad's dispute with her, and groceries. I'm wondering if anyone knows any effects this could have on me. I'm already borderline antisocial when it comes to family, I'm panicky, I'm hot tempered, I'm socially awkward and can't contribute much to a conversation, and I'm lazy. I also feel like I'm not ready for the world, for when I move out, since I've barely been out in the world and taught useful things, like managing money, etc. Thanks for reading. I appreciate it.
