Ghostly sick

A man who can feel the presence of other beings not able to be seen by anyone but himself.
His situation becomes a great deal of pain after a calm few days, he was finally able to get a job and enjoy a day with other human beings (even though they are somewhat rude).
His relief was short lived....

He lives in a small apartment with barely any furniture but a massive discount on rent since the neighbors are a bit sketchy to most people.

What can he do to stay sane on a daily basis with nobody to talk to?!
