First of all I'm going through a rough time right now and am feeling very weepy anyways so I'm not sure if I'm overreacting and I might be. You can tell me if I am.
A bit of background - I have Aspergers syndrome however I would say I'm pretty good at covering it up as I have good coping mechanisms in place. Usually most people would never be able to tell that I have it, sometimes I might come across as a bit odd and quirky but that's it. However because of my Aspergers syndrome I do struggle a lot in social situations - the way it is for me is that I often don't always know what's appropriate to say or when it's my turn to speak and have had some problems in the past where I've just said what's on my mind and upset or offended people. I get around that simply by staying quiet until I can get a feel of where I am and can then start mimicking other people. This of course leads some people to think I'm shy which I'm okay with as I'd rather that than saying what I think and then upsetting someone.
Anyway, I started my new job in January and I thought I was doing pretty well. As usual I've been spending a good portion of my time figuring out the social rules in this environment so haven't really been conversing much until recently however it's not a social job anyway so my boss and the woman who has been working alongside me and who has essentially been my mentor has said this doesn't actually matter.
There's a woman who pops in from another department every now and again and she usually stops for a chat with a couple of people before she leaves. I haven't spoken to her though - I'm usually at my desk working. So today she pops along and again I'm working at my desk. She talked to a few people first and then walked up to me and I, thinking she wants me to do something, asked what I can do for her. She then smiled and went "so you do talk!" Before I'd had a chance to answer she then turned to the man who sits opposite me and said "she can talk after all. I've never heard her talk, I thought she was a mute. So what's wrong with her then? Is she foreign? Is she shy or what?"
I think this upset me because she sounded like she was mocking me and I don't like the fact she asked him this rather than me. She then spent the next ten minutes trying to engage me in conversation, all the while throwing comments in here and there about how shy I was and trying to sit next to me (which made me panic slightly as I don't like people getting close to me and touching me, etc) but she just laughed at how panicked I was. She only stopped when the woman I mentioned above who I've been working with told her to clear off.
I then had to go to the toilets for a cry 
, partly because of the stress of engaging in so much conversation like that unexpectedly and partly because things like this remind me how much I hate being the way I am and how much I wish I was normal.
I'm still upset about this now but not really sure if it's because of what happened and how people will always view me as odd or because I hate having this and not being normal.
I know I'm overreacting actually.
