Initially posted this to the wrong thread.
>>1First off, guidance councilor.
Second, help her find hobbies with a community, like Wargaming/LARPing, Car restoration, Firearms, a chess club, Sports, Videogames that have a world chat like World Of Tanks Blitz used to have (at least world chat) or, potentially, show her here.
As silly as it is, it helped me get over some shit (not self harm but other things)
Don't force her.
Just invite her frequently.
Hell, doing it together may even help.

Just find her a good close group and do your damnedest to help her get in or form her own.
