ok you cant say you CANT do these things, yes you can theryres no such word as cant!! you have done them before and can do them again all on your own, start setting yourself goals just small ones like maybe takin the kids to school one day, i mean if there was noone else to take them you would have to you wouldnt let them stay at home because of it would you???why do you panic when your on your own?cant you get a friend to go with you shopping or a "safe person"?
no your kids would not be better of with the dad, i mean your there mum and they need you and always will. i am the same very touchy and moody and shouting alot, the best thing to do is if you feel this way is to walk away.
i personall think for councilling that if you do want to go for it you have to want the relationship to work and have your heart init, if its not i do nt see a point.
i have been in a bad relationship and you have to ask yourself questions;
are u happy? why are you still init? how would your life be without them/with them? are you in love with them?
but please dont stay with someone just because of the children, i did and was in a viloent relationship because of it till i had enough. you only live once so make it the best ever.
what are the things that ake you happy, reading? walking? spending time with your children? exercise? spending time with your mates?
i do feel the same at the moment i get very down at night time but i try to keep myself busy otherwise i just feel anxious and it ruining my life.
please try to be happy were all hear for you.
