Dreading an upcoming party because I'm socially inept...

Hi I'm new to this site. I saw a notice about the National Autistic Society at my school, so decided to further check out their site and stumbled across this community. This has all happened at the right time as I'm struggling at the moment.

My parents are throwing a party and I'm struggling with this because I'm a social train wreck. And at parties there's always loud music and it lasts for hours. I speak from experience here of my parents past parties. 

Last time there was a party I set my tent up at the bottom of the garden and camped it out. Amazing experience! If you haven't camped then definitely try it...you won't regret it! I love camping, being out near nature. Even in my garden it's surprising how much nature is around.

I would go camping this time but my tent got sold last year. It was an accident apparently but I have a suspicion my mum did it intentionally so I can't escape the party...she thinks I can overcome all my autistic difficulties if I face them with a positive I can do it attitude. 

If it was dry I'd just sleep outside anyway. Nothing better than sleeping under a starry sky. I used to do this with my Gramps before he died. But it's pouring down all day today. 

I'll shut myself in my room but there will be the loud music and family invited to the party just barge in my room and start talking to me. It's literally the worst it really is. It's only a night and I know I probably sound the biggest moaner ever but it's really hard for me to get through things like this. 

I'd love to be able to enjoy parties and talk with my family without getting intensely anxious but sadly I don't ever see that being a possibility for me. 

I need a tent or a lock for my door.
