I might have had social anxiety throughout school and to some degree might still have it,
sometimes I am just really awkward in-front of people and I can't quite figure out why.
Sometimes my words don't come out exactly as how I had thought them they either get twisted around or I speak too quietly and mutter them out, meaning I have to repeat myself, occasionally even more than once making the whole situation pretty embarrassing.
Other times I just feel very self concious when I am out by myself, terrified by all sorts of things like the way I look to people, my posture but most of all terrified I will be seen by someone I know.
I also usually have to think everything through first like what I am going to say to people, I hate having to approach people to ask something or buy something. Used to be much worse though there was a time when I would have struggled to know what to say/do when doing something really simple like getting on a bus/train and buying/asking for a ticket, or phoning for a taxi ordering a takeaway or buying a cinema ticket. Sounds really stupid!!!
Obviously you get used to doing things though and they become much easier, I still have to kind of perk myself up a bit though when having to do something which involves approaching people and asking for something. I have to fake self confidence.

The only things I can really relate to on it are:
Acting, performing, or speaking in front of an audience (although not so much speaking).
Urinating in a public bathroom
Entering a room when others are already seated
Returning goods to a store for a refund
Calling someone you don't know very well
Using a telephone in public
