Just because someone has personal issues, that does not give them permission to treat others like crap or mooch off them. The OP is a person too. And they were hurt by their friend's selfish actions. And even after the friend went home, they offered no explanation and no apology.
Why the hell should people be more understanding of this "friend"? From the info we have, this person is an ass who treated the OP badly. Nobody has any right to do that, disorder or no disorder. If the friend does have an anxiety disorder or mental illness that is so bad it makes them incapable of offering thanks or paying their own way, then maybe they shouldn't visit other peoples' houses until they get a little more control over their illness.
