And just as everyone else in this forum has posted, I've been having a stressful week. I'm posting this, because, one, I really need to just, tell someone. 
and two, I kinda want advise on the stress. This is really affecting me, especially my sleep, which I already lack in, my emotional state, and my all health. Anyways... here we go.So, if anyone knows, my parents are seperated. Not legally divorsed yet. Why they aren't? I don't know... Anyways, so, my dad kinda dates here and there, but for the 3 years my parents have been apart, my mom has seen this one guy... Jeff.
I HATE him, with a passion. A DEEP passion. And it's not only because of the whole "oh, were divorsed/seperated and were gonna see other people" thing, I, have, reasons. He has been a RUDE 
and I mean, RUDE, person, to my mother. Not psyhcially. If he ever hit her, I would be in jail for serious injury to the guy... Anyways, back on subject. So, I mean, yeah, it's two people dating, so what? Well, they are... well... they have dated, broken up, and go back together again, about... 7 times? NO LIE!! I count 7 times =_= if not more. For me, its SO stressful, because my mom is all depressed... 
That's, kinda of a back story. Here's what happened today and yesterday.
Yesterday. My mom picked me up from school all and stuff. Last weekend, my mom broke up with Jeff for SOME reason... Hell I don't remember.
So she picks us up yesterday and goes "Well, on Monday and Tuesday, yes, I did stay with Jeff." WHAT?!?!?! I was pissed off like HELL then. NOT, a happy camper. So me and here didn't talk because I jus plainly told her "You two where broke up?! Wth?!" Blah blah. Then later that day, were decorating for X-mas!! 
It was fun, me and my mom were...talking finely. Having a GREAT time! ^^ Then, I go to take a shower at around midnight. When I get out, omg, guess who is there?! 
Without even TELLING me, I came out to see Jeff, his friend Jerry, who is drunk and my mom, standing around and laughing. Ticked me off... I was chased outta the living room with all my stuff outside. I figured out this morning the three snooped around on my laptop..... 
Today. So my mom picks us up again after school to take us home, and were all fine till she mentions Jeff and her going out. I don't say a word. She acts me whats wrong, and I go OFF on her. She and her I fight, just a fighting. Ughhhhh.......
So I get home and my mom doesn't even talk. Jeff comes, picks her up, and the leave. Later, on dad calls. He can hear how horrible I sound and he and I talk. He tells me how he sees it, which he true to a point...He says "Your mother and your sister are JUST alike. You and I are alike too. See, your mother, she sees the good in people. She's able to push back all the other bad stuff to see the good. You and I, we don't. We see the bad, and just don't deal with that crap!"
Which, this is one reason I do hate Jeff. I see the bad in him, and hate him. All the guy does is sits on his butt at bars and drinks till he is drunk. He ALMOST cut his finger off!
He even came to church once, drunk... ... what my mom sees in tha guy, I do not know.I'm SOOOO sorry for ranting. I'm...over-sensative, but I NEEDED to tell someone. I already told a few friends, one of them being SimbasMate, but I needed to just, get it off my chest. Ughhh....
I don't know to do anymore! I've talked to my mom, and she yells at me. I told her one time I didn't wanna come over anymore because of Jeff and she got even madder... Not much I can do... Ughhh!! I think I'm done ranting..... *sigh* Ok, there's my stress.... 
No one should be liable to have such horrible stuff happening to them. What I would do is try to explain to your mom as plainly and nicely (lolz) as possible. Tell her what you think of Jeff and why you dislike him. Hopfully, your mom will understand. If she doesn't, you need to talk to Jeff. Tell him how you feel about him kindly. You don't want to offend him. I hope this helped and that you feel better soon Nighty! 
I would of stayed with my dad, but he was busy. Not only that, my mom gets mad at me when I DO stay with my dad...
