Awwww that is not good EB, I can understand why you feel disappointed. Maybe your colleagues didn't want to see you go ? Charity shops sell wonderful clothes at a fraction of the shop prices, and you will manage your finances somehow. Whenever I panic , I always manage to get by, not so comfortable maybe but it is only temporary.
As to your new job, you will probably fit straight in and be fine from day one. Chin up girl, go get either a gin or cup of tea and think of how you can treat yourself in a couple of months xxx
