Is it normal to have a shitty mum and brother?

I know there's a lot of "I hate my mum posts".

Probably because in general they're one of the worst parents and fucking lazy too. (Just my opinion, and not all mums, just quite a few).
My dad works from morning till the next day, and buys us food too.
If he didn't we would be on the street. Mum just makes the stupid excuse of carrying me for 9 months, as her help for our family and me. We're in serious dept, so me and dad work, but mum and my brother doesn't want to help.

It's my birthday today and my mum and my brother(he's a mama's boy) ruined it.
She told dad I said mean things about him and shoulted at me all day like a crazy witch. My mum and my brother didn't even wish me happy birthday.

I'm sick of her I feel like she's the cause of my depression, I didn't even want to dance with my younger sis today (we do dance as a serious hobby in comps but also for fun randomly).

I just feel like killing my self, my exams start in 3 days too. Couldn't even study today mum shrieked at me to pick up shit for her she was too lazy to get her self, right next to her!

She has hit me when I was younger, and calls me fat when I'm normal and she's obese.

I feel really shit, and just want to lie down and waste away....

What hurts the most is that I can't tell my friends or I'll just be a miserable burdern on them, and they'll all leave me like my old ones did a few years ago.

I don't even have enough money to move out this house either!

My sleep is fucked up, I can't sleep at all, only a few hours till I stay up again.

Psychologist are crap! They keep asking me "how do you feel?" When I really feel like saying back to them "bitch how would you feel if you were me!? Are you retarded?!" Even had one tell me when I was a kid, "I can't help you, I'm just here to check on your well being." And a month later a girl going to the same therapy killed her self in a car crash! Probably because they told her the same thing!

Alway gotta put on a stupid fake smile when I go out, when I really want to stab my self in the face and die.
