Hi there ... My heart goes out to you ... Bless ya heart ... Life sure ain't fare ... I can't imagine how you are keeping things going ... You must be at your wits end , juggling with so much ... 

McMillan have help line where you could get help with practical things when it gets too much .or need someone to talk to..... Have you anyone close who you who can call on or when you just need a hug ... Yes he does have a right to feel angry but it's not fare when it effects the one person helping him ... May be he needs someone to talk to too , as he may be holding his feelings in so much it comes out as fustration ... If he knew how his little ones need him to stay calm , maybe when he's nice and calm , telling him how fragile their feelings are right now  ... I'm clutching at straws here in trying to help ... I hope someone can give you better advice then me , if they have been in your situation ...

Please look after you kind heart ... I hope you get some help on here or help line ... Please keep in touch coz in writing things down it may ease it a wee bit ... Sending you big hug .. chrisie xx
