This is quite a first world problem and I apologise in advance, but it is causing me sleepless nights and daily panic attacks and I could really do with some advice/perspective.
We recently bought a house using a combination of some money my mum left me when she died and a much bigger mortgage than we would otherwise have chosen. We did this because it was a house of a size and in an area which don't come up often in a price bracket we could afford. The plan was to sell our smaller house and use equity to reduce the mortgage on the new house. Literally the day after we exchanged the Iran war started, which has caused me extreme stress that has never really abated. Had we been due to exchange any later we wouldn't have gone ahead. To add to it, the buyer on our house has just pulled out for the second time (long story) and so we will be in the position of substantially higher outgoings for an indefinite period of time and a lower eventual sale price. My husband didn't really want to move and so while he isn't blaming me I feel wholly responsible for this situation and the money we are spending and now I'm starting to hate the new house which suddenly seems much less nice than before. I don't know what to do to pull myself out of this spiral of doom and panic which has got to the point where my husband says he dreads coming home from work because I am always so upset/panicked etc.
