That really entails a tough answer as it is somewhat a family matter and I havn't been in that kind of situation before. But what I could advise is what I'd do first if I was in your situation is I'd keep all my collections first out of their sight and be discreet on any TF activities for some time. Just to let them cool off until your current status stabilzes (meaning just to give them an impression that you're solid serious on looking for a job). Selling your collection "may" cause additional burden but maybe just for a bit of time as I know some members on the board had currently done so. As hard it is to tell how your relationship with your parents are, I'm not suggesting that you sell your collections immediately and give them some more time as possible.
Otherwise, if that doesn't work, kindly post it here first under the sale yard. 
Best of luck mate!
