Don't hate life. You just mentioned a couple of God given reasons to live. Your child is one and the fact that God entrusted you with your child is another.

You may not see a point for your life but God did. That is why He gave you life and made the sacrifice for your eternity.

Be blessed and love your blessings. Your child needs you. And remember, life isn't about us.

Just emerge your self in GODS word pour your heart out with the truth of what you feel,GOD,will fill you with, his peace and joy,emotions are signals, we need to tell us things, tell GOD everything let him take over,GOD BLESS YOU, strentghen you, comfort you, read psalm 103,,a lot keep an open bible so you can refresh yourself, with the real reason we are all here, and why everything on earth was made, for GODS glory,,
I fight depression,constantly,
but fight its a good fight,you have been bought by GOD himself,,satin doesn't like that,
he is constantly,trying to win you over to the worlds way,,
saturate your mind,so you know what is really real, then just like JESUS,you can say,,it is written,and get thou behind me satin.

Your son needs to be the reason you live life. God gave you his most precious gift. Start with that.

Hold on sweet child of God. Take each minute that passes and think to yourself " what's the next right thing I'm supposed to do?" Then take a look at influences in your life. What is the source of your dpression? Is it something you with God's help, can change?
