I am ready.

I am so sad and ready to quit. My son has been staying with his father because I can not handle him. I am sad sad beyond belief.Meanwhile I have my 15 year old daughter who I love more than life here with me. But I am sad, depressed and tired and want to quit. I am 52 and have had the damn depression since my teens, sometimes treated, most times not treated. I just want to go to sleep and not wake up.
