Glad you're physically alright Julia, the rest will follow in time. You'll get there, just hang in and let time (and lots or rest) do it's job.
About the house... I've bought houses, even being a JW with my ex-husband together. But if you have to get a mortgage for it, please don't do it! If you can pay for it, so it will be YOUR property it's okay, but as long as you have to involve a bank... better not! We've lost a house to the bank twice. It's a ruthless game they play and they play to win. You think it's your house, but as long as there's a mortgage not a brick in the wall is truly yours!
We're happily renting now, no more worries and if we want to move house we can go whenever we want, without the struggle of having to sell a house first (and the risk of not being able to sell, like we experienced, and being stuck with double payments for months or even years and finally having to face the worst case scenario, like bankruptcy).
