My aspergers is ruining my life?

I was meant to go to this big gathering at a pub. I stepped out on the train station and I saw atleast 40 people outside, blocking the entrance of the pub. I tried to calm myself down to try and make myself go inside. It was all too much plus I know that I wouldn't know anyone. I hate my aspergers for making it difficult to go inside, it's ruining my life and just stopping me to socialise. It's killing me.
