You will quite possibly go mad before things get better

I nearly stopped the whole deal when our conveyancer went feral; she sent contracts and documents to sign which confused me, so when I called she'd abuse me for being a bit slow, and then wouldn't apologise when the errors were in her not sending the documents! No wonder I didn't understand! I got my own back by asking the bank to never refer customers to her again

It'll get hard emotionally and financially, but one little thing at a time and you'll get through. It's worth it.
