A Bronx mother is pleading for the return of her missing 43-year-old son who suffers from bipolar disorder and schizophrenia.

Barbara Felder says the last time she saw her son, Michael Daughtrey, was Feb. 21 at his home on East Gun Hill Road in Williamsbridge.

She says he was heading to a mental health treatment appointment in Riverdale, but has not heard from him since.

Felder says he lost his phone, but had an index card with her number on it, as well as the number of his uncle.

Daughtrey turns 44 on April 29. Felder is pleading with anyone who may recognize him to contact police.
