I think we've all done this at one time or another.
If you haven't worn it or eaten it, you can ALWAYS return it! The people you care about that you've bought the gifts for really don't want you to go in debt to show them how much you care about them.
One of the things I've learned to do it to never, ever take my debit card with me on a fun night on the town. I tuck the amount I plan to spend in a pocket in my purse and when that's gone, there ain't no more.
Hope things work out.
