Context: I got dragged to town today , I did n't want to go but anyhoo . The weather was crap , the town was crowded ( I have minor agoraphobia and social anxiety problems ) so that was not fun . Decided to bring a pile of old books I tried to sell earlier this year , still no buyers so they 'll most likely go in the bin and all that . Saw a few people from school randomly wandering the town , looked for some cd 's , games etc but there was nothing there I wanted . But the main problem today ?

Question: What may be the reason fir the anxiety ?
Options:
0. None of the above choices .
1. I want to ask a girl out .
2. I got a bad grade .
3. I do n't like big crowds .
Answer: 3
