This! Exhausting is the word that sums up the social anxiety experience for me. Even when I'm in a good state of mind & feel up to interacting, doing so is so doggone tiring - it's like running a marathon whilst balancing a stack of wine glasses.

As per magicalprince's post - limiting exposure to things that I genuinely want to do, seems to help - forcing myself to do things I hate, seems to set me back. Sadly, that approach is not always possible...
