Don't worry about abandoning the sleeping pills as there is no shame in taking them. You have been dealt a massive blow to your ego. If you broke your leg, you would get plaster on it. Taking the sleeping pills is temporary , until you feel stronger.
If you sit at home wailing and feeling sorry for yourself ( which you have every right to do by the way) it will not make any difference to the situation, one way or the other.
So you might just as well get out and try and enjoy yourself. I would explain to your Mum what you are doing , as if you go from a sad lettuce leaf, to a mad flapper over night, she will be puzzled.
Call in all your favours from all your friends. Ask them to go out. Go and have fun. Try odd things like go cart racing, trampolling etc. If you have no friends around about get a temporary job, one night a week in a busy pub. Get your lippy on and enjoy being out.
If your babies can go to a nursery for a few hours then get to a gym. Walk very quickly for at least two miles a day and play your fav (cheerful) music through ear phones as you go. Get fit mentally and physically. It helps to feel and look your best to do combat with the shite.
DONT CONTACT HIM? CUT ALL CONTACT?
So far, he knows exactly where you are......you have been a doormat.......don't answer any of his texts, or just answer curtly. This is war and he is the enemy.
So now is the time to reinvent yourself. Don't have a dialogue with yourself that starts....I want him, he hates me...I am not good enough for him....he wants other women more than me,....etc etc. This sort of thing is beating yourself up.....why ?
You are totally innocent of any wrong doing, so why should you beat YOURSELF up? He is already doing a good job, so why do it to yourself on top?
So , a horrible thought comes into your head.....STOP it, scrub the floor, listen to your music and dance around the room madly, run around the block. Etc but no thinking negative thoughts.
Your mind controls your body, so you can do this.
You are going to get past this and one day when you are back on your feet with DCs who love and respect you.....you will have contempt for the lying SOB who dared to treat you like this.
You are a Princess......remember ! and you deserve better.
Hugs
