I wanna die (really really bad life)?

I have been so freakin pissed about my life and I'm very depressed about the future and theres nothing to change it. I am in a language therapy class I don't even need at all they're just for brain dead fu****s. Hell, there are people hell alot dumber than me that don't even need to go. Also my brother who has autism is going to my school next year like how the F*** am i going to be popular if he is there making my popularity worse.Also it effects stress I have to put up with every damn day. My older sister wants a puppy and we got 1 dog and 2 cats already we got a puppy anyway. WHAT THE F*** IS SHE THINKING IS SHE LOSING HER DAMN MIND!?!?!?! I am feeling sick of living. No one will give a crap about helping my problem or take me to a specialist. I feel my life is over and pointless I'm going to a crappy college.... having a crappy life and if i get married and have an autistic child I am going to be especially pissed and my life would be official FU**!!!!!!! someone PLZ help my problem. It seems that only fake and imaginary things make me happy.
