Good afternoon everyone

I have a friend who has social phobia and for years iv been trying to help him get out and break the cycle of sitting at home and not doing anything and then getting down because he's not been getting out. Im going to be honest, I dont understand the phobia and I was hoping I could get him one here and maybe start to improve by using pc. Ive only just started pc myself and i was hoping i could ask people who know better then me if there is a good way to encourage him to get involved?
