Supervisors are supposed to know when a situation may fall under FMLA, and they carry more of the burden of that understanding than employees. I wasn't bringing that up to explain the process, merely to help the OP with his particular circumstances. He informed his direct supervisor of his condition, and the supervisor did not point him in the right direction. He can use that fact to support his attempt to have his prior absences covered by FMLA when he talks to HR.
