I have a mentally ill sibling who says, "Everyone ELSE needs help, NOT me." I think that is worse than knowing you need help... if you know you need help you may eventually seek it, but not realizing you need treatment when you do can turn the world against you and leave you acting like one huge martyr (as my sibling does). Everyone else around the person suffers.... and nobody can convince him/her that HE/SHE IS the problem.
