Attention gaining device: It is finals week and you have been panicking about passing your classes for the past month. At times, I would not be able to pay the full amount of my "rolling account," and so I would do a balance transfer.
If you have taken loans to build an asset, such as a house, or are using your credit card responsibly to build your credit score, then it is good debt.
Balance transfers do normally carry a fee, but the priority under the emergency circumstances of grad school is not to minimize your debt load, but to maintain your ability to keep rolling over your debt on favorable terms.
Making sure to keep rolling over balance transfers with new offers does have the long-term benefit of minimizing your interest payments, but in the short term, it also reduces your minimum payment, hence helping the all-important liquidity.
Your first goal may be to create a budget to get a specific problem under control. Rather than get bogged down by thoughts of never getting out of debt, imagine the amount of stress you feel decreasing as your debt load gets smaller and smaller.
If any of these effects of stress are causing you duress, please, consult your physician immediately. This type of stress is called eustress.
