Can you see the early childhood family nurses in your area. They usually have a great support group. I had a mental health nurse take such good care of me and put me in with a group of mums in the same boat as me and I would be lost without them. Sometimes being in a miss matched group can make you feel worse so stay away from them. Its not their fault nore is it yours. But I have to admit I dont know where I would be without my mums group!
Good luck and a huge hug! Think of it this way, would you rather be having to bring up a child in a loveless, possibly abusive relationship or on your own where you can control your life and your childs life. Its just you and your child and you dont have to worry about trying to please a demanding man aswell. Sometimes I have to say I envy the single mums... Embrace the good things in your life and know that you have the love of your amazing child and you dont have to share it with anyone!
