Thanks for all the replies; it means alot

to shed some more light on the situation- my mother died when I was in 8th grade and i was extremely close to her. I never cried until a year later (my dad mentioned it to the pychiatrist so i thought it might be worth mentioning)
also, my relationship with my dad is almost nonexistant. I don't like to talk to him at all and we have nothing in common. He is more like my sister. He comes home late so i pretty much have the house to myself (my sister goes out with friends all the time) until 11 or later.
The only thing we can talk abotu without being awkward is the weather. To be honest, when it is his time to go, i hope he isn't going to buried next to my mom because id only want to visit my mom (is this kind of thought bad? i feel giulty for thinking it)

My sister- I hate her. I honestly cant stand her. I clean up after her, she's constantly mean. She's incredibly snobby and even though she lives with me, we have not a spoken a word to each other in almost 3 weeks now.

this is why it is hard for me to tell my dad: I do not think i can do it. I actually saved up and went to a pychiatrist myself, but she ended up contacting my dad about it (even when she sworn she wouldnt and told me whatever i said stayed in the room secret safe)

I have no idea what to do becuase I can't wait a year when I'm 18...everything is getting worse...
