I'm angry at my parents; except that they're my parents and I love them and I don't want to be angry at them.
You can be angry at them and still love them. It's a weird place, mentally and emotionally (particularly if you were raised like I was and you weren't allowed to be angry at your parents), but -- you can love them and still be angry at them. In fact, you can love them, be angry at them, AND never express that anger TO them (if doing so would be totally unproductive).
Eventually you have to feel your anger, even if you think it's overwhelming enough to destroy the world. (Remember the episode of Angel -- stay with me here -- with the woman who had telekinetic power, and an abusive shithead of a father, and when the father showed up, all the windows in the Hyperion exploded out, because, hey, traumatic telekinetic reaction to abusive shithead father? My anger felt like that, like I would blow shit up if I let it out. It still feels like that sometimes, like I could Hulk the fuck out and destroy the world.)
I also don't want to be like my dad.
I feel that. God, do I feel that. I just tend to think that, because you're actively dealing with this, you're way ahead of the game. You're extremely likely to be aware of any tendencies you have to be like your dad, and to deal with them.
Having fucked-up parents (who you still love) really blows. Hard. And I wish you didn't have to deal with it. But, in case you don't have perspective right now, you've been dealing with it so well. You really, really have.
