Good point.

I have social anxiety, as well. For me, it's a case of certain situations giving me anxiety, but general social anxiety is a thing for me, just at varying levels of stress; some of these levels I can power through, others I can't or just refuse to because it's too unpleasant/unhealthy.

What I can do:

I can occasionally (kinda rarely, if I'm honest) walk to the center of town (15 minutes or so) wait at the bus-stop where many other are also waiting (5-10 minutes waiting) then take the bus to a another town (45-50 minute ride) then get off and walk to my brother's place. (10-15 minutes) BUT that's a LOT of anxiety for me, and something I do rarely for a reason.

I am able to go to Tesco, 7 or so minutes from my house, but, depending on the time of day, it can be more, or less stressful. I do tend to avoid this, sometimes even not eating much until I feel I can go there and get some food. (lately, I've been doing sort of OK, but I slip up sometimes)

I am able to go with my dad to various places, like a big city heaving full of people (very rare) or to town (uncommon) or to Tesco near my house (occasional).

I can walk 44 minutes to some place I've never been before, past houses owned by people I strongly dislike or have other issues with, and meet people I've never met before, to start a job doing something entirely new. This was, however, a first, for me, and it was definitely scary, but I somehow made it; I feel like it was a miracle, to be honest.

I can go out into the garden and play the guitar, knowing my neighbours, anyone passing by (they can't see me) and anyone who's home could hear what I'm playing. The anxiety affects how I "perform" with regards to the guitar, though, and quite a lot... but I'll get to that in a moment.

What I can't do:

I can't go see bands, because I would be surrounded by people I don't know, in places I don't know, with so much noise and lights and ... too much stimulation; I would be overwhelmed, in a bad way. I've been to see a band once, I believe, when I was quite young; it wasn't overly big (big for my town, but still) but I didn't enjoy it. (the music was fine, it was being there that I didn't like) I remember, at one point, everyone stood up to cheer or something, but I refused and stayed seated... I didn't know it at the time, but that was social anxiety keeping me there. Too much stimulation. There's just no way I can have a decent time like that.

I can't be in a band. (serious one that plays gigs and stuff) I've had to turn down a great, locally successful band (as lead or supporting-lead guitarist, because of it. I was very briefly in a metal band, but I suspect the social anxiety had something to do with my leaving it.

I usually struggle going anywhere I haven't been before, know nothing about, and definitely if I'm going to these places alone. If I'm with someone it helps, sometimes even completely, although that's quite rare. Such is the nature of these sorts of MH: there can be good days and bad days.

Although I could go visit an old friend of mine, and other old friends, getting back more of a social life that I used to have, I haven't, and may never do as such, and I suspect social anxiety has something to do with that. (also, bad history with them)

Social anxiety is definitely a reason why I can't/don't work. I get paranoid saying "can't" because... what if I can? I'm sorry for saying this, everyone who is severely physically desabled, but sometimes I almost wish I had no legs or something, stuck in a wheelchair, so that way I wouldn't be doubting myself and what I can or can't do; people could see it, I could see it. It would be proven. I hate mental health crap because it's almost like it's not there, but IT REALLY IS.

There's more of course, but that's general gist.
