Kim, you will learn through time and with experience that two days, never mind two weeks are ever the same.
I think paying your bills is more important than a night out so I cant say you did the wrong thing. You have to think of your family and their welfare before you think of your own social life.
I would not bank on loads of business now for quite a number of weeks. For some, January can be fairly busy, but not for all, but February is usually dire right across the board. You may get the odd exception to the rule but not many. So I would suggest saving all that you can over the coming months so that you can fall back on your savings when required, especially as you probably still have a fair amount to pay towards that upcoming wedding.
I, and many other longer established WGs organise one of our holidays during February when we know we wont be losing as much as we normally would in other months.
