As a side note, there's this other manga titled "Furara Hitori de Dekimasen" (Furara Can't Do It By Herself) that is vaguely similar to Bocchi in concept, in that it also stars a character with extreme social anxiety who can't handle doing things on her own. But I couldn't even enjoy it because every situation ends with the other characters giving in and fixing the problem for her. And that's something that I think sets Bocchi apart for me, not just from Furara, but from pretty much every other series that deals with any sort of social anxiety (I'm looking at you watamote) or hikikomori.
Although somewhat cutesified, it's a fairly accurate depiction of social anxiety, but beyond and above that, it shows her seriously working to overcome it, and (here's what really sets it apart) the characters don't enable her behavior, never force her, but actively support her and aide her in doing all these things on her own, so that she's actually able to grow.
This series is actually a really good guide on how to handle friends with social anxiety.
Though Kai's method is a bit too extreme... (But it was the push Bocchi needed, and I doubt anything else would have done it, so I'm conflicted.)
