My first post here on Mumsnet but I couldn't go past this post without saying something.
I know to some extent how you feel. My husband recently announced also that he no longer loves me, after 16 years together and 3 children. I don't drive, have no income, have an injured back, was at my lowest point ever when he told me AND suffer anxiety to the point I have no social life at all. It feels like one big horrible mess. Some days I don't want to exist at all, I feel worthless, like there is nothing left in this world for me and even my beautiful children aren't enough to make me want to stay here. I feel angry, betrayed, confused and helpless...and then I get mad at myself for feeling so pathetic.
Here's the thing though...as much as it hurts would you really want him back? How would you ever trust him to not do this again? If he said he loved you would you ever actually believe him? That's no life for either of you. I want my husband to be happy, but I have to accept I no longer make him happy and having him stay with me for the sake of pity would only bring resentment and ill feeling about. Is that what you would want for your kids to see between you both?
I hope you can find another GP and get some help, build some confidence within yourself (and yes I know that is hard with anxiety issues) and start to figure things out. You are lucky to have your parents there for support, talk to them, lean on them and let them love you.
