Dear,
I used to feel depressed when i was younger. I must say it is aweful then. I felt that there was no need to live anymore. I heard a message from a Pastor, that depression is an evil spirit and from the devil. I gave my life to Christ and got born again. Its a thing of the past now. I live every day, knowing that i was born for a reason. I never have a blue day anymore, cos Christ in me, the hope of glory.
No doctor can help you, they can only try, true help comes from God. My advice is that you get born again, and align your purposr with God's purpose for your life. There is so much with knowing who you trully are in Christ Jesus. Joy unspeakable would be yours. I encourage you to join a Church. Doing the time of my depression, i started attending Christ Embassy. Its not my church, but their messages are powerful and would really encourage you. I have been there and i know what you are going through. I would say a word of prayer for you.
