In need of help

Hello  I an new to this as I have never needed help like this before . I am a widower with three children on a disabily , I have been doingwhat I can to keep what I have and as well as keeping my kids happy with what the need . I am really starting to have a very hard time keeping up with all my bills , the main one is my rent to keep a roof over my family's head. I have no where else to turn I have tried many places to find the money I need to stay here it  has been a very difficult road for me since my wife's passing from cancer .  I have been the one that always helps people in need and never asked for anything in return Untill today .
