Need advice to deal with my parents! I NEED HELP URGENTLY!?

I dont know what to do with my parents anymore...my dad is having a "i-hate-my-daughter" season and everything i ask with as a favor or tell him or do is always wrong, he looks like he wants me the furthest apart from him...my mom is ok with me but ever since she heard that me and my boyfriend had sex (we've been dating for more than 2 years now and thanks God she at least didnt tell my dad about it) everytime i tell her that im going out with him, she makes me feel miserable before letting me go, making me feel like if i was a whore...i dont know what else to do to please them, i get straight A, i try my best to have a good relationship with both of them even if that involves sacrifices, i prefer to be at home rather than going out if that can avoid fights...i dont even go out as usual as i did before because im afraid of whatever they tell me when i ask their permission...im 17 by the way and i need urgent help, i really want to mend the situation with my dad (been happening since about 2 weeks ago) and most of all, the situation with my mom (been happening for 2 months now)....im really desesperate
