Long term emotional effects of Depo provera

Hello, I was taking the Depo for around 3 years from the age of 21-24. A year ago I stopped taking Depo after a doctor told me I shouldn't be on it for longer then 2 years or until I am 25 years. Once I stopped taking the Depo I put on 8kgs, had suspected polysistic overies and most importantly a complete change in mood and personality. All of a sudden I have no emotional response to anything anymore and can't even put myself in other people's shoes or think clearly about what is right or wrong. Can someone please help me.
