I'm writing this now as I am absolutely terrified of falling asleep, I started lying down in bed about 2 hours ago, upon closing my eyes everything rushes to my head, gcses, family expectations, family lifestyles, material belongings, my cats, my brother guinea pigs, my chickens, my head, hair, eyes, teeth; literally anything a human can worry about, I started crying (i have done this in the past) when I try to fall asleep all I can think about is the house getting robbed or an accidental fire and the loss of everything I know and love.
Death terrifies me, memories and thoughts can be gone in a split second and even the thought makes me tear up.
If I don't succeed to the quality I want in my gcses I'm scared to even think of what thoughts may cross my mind and I end up spending more time worrying than revising.
Not sleeping means I mess up in school, not taking things I properly or falling asleep, I won't be able to revise the subjects I wasn't able to learn.
Why are my parents divorced, why can't anything go right, I just wanted a happy family.
Being male sucks, none of your friends really lend an ear to what you're saying, they'll kind of just accept it at face value and perhaps use it againt you further along down the road. And if you have any female friends they'll think you've come off as clingy and leave you in the dust, forgetting about you and I'm all too familiar with both of these scenarios.
People terrify me, for the reasons above and the fact that I feel like I'm always being judged, someone's always looking at me, silently thinking "whys he so red in the face" when I can't help it.
I have friends for fun in video games but nothing ever feels like that one friendship everyone has, where thers always the dude/girl that they can lean on
I don't want to put more of a burden on mum as I already feel like a massive autistic tumour attached to her skull (I am actually asd.). 
There's so much more that I could go on about, but I don't want to type any longer, I don't know what to do and that makes me anxious, im sorry if this wasted your time anon, thank you for listening.
