Have I got aspergers syndrome or OCD or something else?

I am married with two children and enjoy socialising with a few people although not too many. I have a good job which I generally enjoy. However, I am anxious and often feel down as I can't read body language very well and if my room mates (at work) don't speak to me I get really stressed and think it's my fault and worry that they don't like me. I often can't understand or recognise when people are being sarcastic or joking and it makes me very upset. Also I hate change and find it stressful. I feel like I'm losing friends and I can't cope with this much longer. Have I got aspergers or OCD or something else? What can I do?
