I'm no expert but you sound depressed, but I don't think that any kind of breakdown is inevitable. I'd advise, no matter how annoying your daughter was being, that you try not to place blame for decisions you made on other people. It will cause friction in a relationship which you need to be good & strong. As a separate issue you may wish to speak to her about how the moaning affects you and request she could help you rather than complain and upset you. But back to the way you're feeling; recall that life is full of ups & downs and neither last forever. Take the situation you find yourself in and try not to concentrate on how things were previously. May not seem like it now but this change will give you new opportunities and new experiences, once you accept it's potential and go for it. Give it a chance, make the most of it, and eventually you'll look back and see why it was no bad thing. We all like to stick in comfortable ruts, occasionally life gives us a kick to stir things up. Check out all the things you still have, family friends, possessions, whatever. You've still got that as foundation. Meanwhile a change in mental outlook doesn't tend to occur overnight, it will take time. And I suspect most of us have experienced not giving a damn about anything anymore and just hating one's life; but life is a gift, you'll find you've plenty yet to do, goals to achieve, in all sorts of areas in your life. Take it a day at a time, try not to brood over that which upsets you, if it comes to mind then acknowledge it and then find something else to think about. And maybe find an interest/hobby to lift your spirits. Perhaps learn a musical instrument or learn about a subject you always meant to know about, or join a social or sport/game club. Visit a show or concert regularly maybe. Whatever appeals to you. And good luck getting out of the sad state you're temporarily in.
