Evidently the anxiety is on the EU and IMF side, not on the Greek one. Greek economy has collapsed since 2009 (in reality back in 1989 due to 8 years of strict rule of the EEC rules - sustained for 20 years by the EEC-then turned-EU). As soon as Greece tried to do something different (in the period 2004-2008), i.e. opening talks with Chinese, signing for Russian gas, opening up ports, the EU and IMF (i.e. US and Britain) rushed in to provoke successively, fires, murders of political, religious and military people, either by accident or by induced rapid-cancer (even the Greek archbishop was murdered that way - judged too nationalist, too Russo-phile), riots and then given the forced rise of PASOK under US-man Papandreou, the crisis which brought Greece, under the careful planning of Papandreou under the EU-IMF.

The whole idea is to sustain the country totally dependent and in a prolonged if not permanent way. For Greece there is not a lot of space. Either out and faced with EU expulsion and war (US will mathematically attack Greece - it won't be the first time, happened in 1974 and indirectly throughout...). The only fear is of Greece breaking loose and switching to a pro-Russian stance. No matter if this scenario is distant, since Greece even it was not afraid of the US backlash it cannot count on Russia (Russia was never a serious partner assuming full responsibility in Greece, this dates back to the 18th century when Russia was keeping letting down Greece with disastrous results), still the US and Europe have taken extreme measures to lock Greece in its current position. Still it is them who are most anxious - which can only be tragi-comic.
