Hi Lissie,
I was in a somewhat similar situation to yours - being a teen, knowing something was really wrong with my family, but having no power or freedom to do anything. I finally moved out when I was 20 and started therapy soon after that.
It's great that you're looking into all of this now and finding out what you can about it. The sooner you start, the better. And just by trying to get more information about it you've already started your own healing process.
Do you have access to therapy through your school? I suggest seeing a therapist. If your family/community is against therapy (it's shameful, it's for crazy people, it's a waste of money, whatever) maybe try to look at it like this - in any situation in life it makes sense to get the advice of someone who is a professional in that field. You need legal advice, you see a lawyer. Medical advice, see a doctor. Here you're dealing with psychology - you're just consulting with someone who is a professional psychologist.
I know you've got an awful lot to think about already, but you might want to find out more about co-dependency. Basically co-dependency means certain unhealthy behaviors that a family develops when one of them has an addiction or mental illness. From what you said about your family I got the feeling of co-dependency, especially that your mother may be co-dependent to your father. It's actually healthier for everyone involved if even one person (you

) stops going along with the co-dependency. The best thing you can do for your family is to get yourself healthier.
I think it's very brave for you to post here and it's great that you're trying to sort this all out. I just wanted to bring up one more point, and I know you've already got a lot to think about, but... I got the sense of you being all tangled up in your parents' problems. Of course that's going to happen to some extent when you're a minor and living with them. But I got the sense of it being more than that. Like you've somehow been taught to take on more of the burden and responsibility than is actually yours here. You don't have to take care of anyone else or fix things in your family. If that doesn't make sense now, that's ok, just keep it in the back of your mind.
Take care, I hope you will keep posting here and I hope you find the answers you're looking for. Oh, and BTW the unreal feeling you mentioned in your life may be dissociation. It's a coping device that your psyche uses to protect you from being overwhelmed.
