I lost my dog of 13 years in June 2 days before my son's bday and who also died. I'm from VA moved to SD to get clean from heroin now I've been here with a meth addiction on and off for 3 years and it's destroying me. I have no friends that don't use me or anyone I trust to talk to. I want it out of my life. I'm hurting inside and depressed. Very unhappy with myself and grieving
