If he does, then he's an arse of the highest order and frankly doesn't deserve you! Anyone can see that you are in pain and struggling and you need him so much. He needs to be there for you, because you really need him. And that's what you do when someone you love needs you so much - you drop everything and you give them what they need.
You need help. You need to see the doctor and get the help that you need.
You have daughters? Imagine one of them was going through this. What would you want them to do? Struggle alone, hiding their pain? Or shout out for help and get better?
You don't deserve any less than your children. And you deserve to be helped for you, for your husband and for your children.
Please. I've been there. I have hidden depression (I had psychosis after my first son was born, thought he had died, thought he was a demon... it was horrible.) I hid it from all professionals, because I was scared. Although I was able to tell my husband. But he did the worst thing - he helped me hide it, cos he was scared too.
Don't make my mistakes. Please. Get the help you need and are entitled to.
If you had broken your leg, you wouldn't hide it,would you? you'd go and get a cast.
If you had a chest infection, you'd go for antibiotics.
This is NO different. It's just a different part of you that has suffered an injury and needs help to recover.
