After the September Uprising of 1923 she emigrated with her husband to Austria. Ljubica had spent time in Vienna and she taught her husband the German language. Later they moved to the Soviet Union. She lived permanently in the Moscow hotel "Lux", where she suffered from depression because of the constant travels of her husband and the inability to have children. In 1927, already mentally ill, she was placed in a special sanatorium near the Soviet capital. The arrest of Dimitrov in 1933 in Germany on a charge of inciting the Reichstag fire exacerbated her condition. On 27 May 1933 she committed suicide by jumping from the third floor of the hotel while her husband was in prison in Berlin.
