As well as thinking of the poitives as bednobs has suggested, I'd start with things you can control, e.g. get yourself a jiffy bag to return the phone in if getting it sent will give you peace of mind, a small price to pay and then something you can tick off the list.
The cause of the camera fault may be the weather therefore only temporary.
February is only a few weeks away for someone to come out and it is a busy time of year, a few weeks is not as bad as a few months!
I agree with bednobs too, if these things are really getting you down as much as it sounds, speak to your GP or someone else about how you are feeling.
