What does the Gita say when you can't decide what to do?

कार्पण्यदोषोपहतस्वभावः पृच्छामि त्वां धर्मसंमूढचेताः ।
यच्छ्रेयः स्यान्निश्चितं ब्रूहि तन्मे शिष्यस्तेऽहं शाधि मां त्वां प्रपन्नम् ॥

kārpaṇya-doṣopahata-svabhāvaḥ pṛcchāmi tvāṃ dharma-saṃmūḍha-cetāḥ
yac chreyaḥ syān niścitaṃ brūhi tan me śiṣyas te 'haṃ śādhi māṃ tvāṃ prapannam

With a heart contaminated by the taint of helplessness, with a mind confounded about my duty, I ask you. Tell me what is assuredly good for me. I am your disciple; instruct me, who have thrown myself on your indulgence.

तस्माच्छास्त्रं प्रमाणं ते कार्याकार्यव्यवस्थितौ ।
ज्ञात्वा शास्त्रविधानोक्तं कर्म कर्तुमिहार्हसि ॥

tasmāc chāstraṃ pramāṇaṃ te kāryākārya-vyavasthitau
jñātvā śāstra-vidhānoktaṃ karma kartum ihārhasi

Therefore, let scripture be your authority in deciding what should be done and what should not be done. Knowing what is declared by the ordinances of scripture, you should perform action in this world.

श्रेयान्स्वधर्मो विगुणः परधर्मात्स्वनुष्ठितात् ।
स्वधर्मे निधनं श्रेयः परधर्मो भयावहः ॥

śreyān sva-dharmo viguṇaḥ para-dharmāt svanuṣṭhitāt
sva-dharme nidhanaṃ śreyaḥ para-dharmo bhayāvahaḥ

Better to do one's own duty imperfectly than another's duty perfectly. Death in one's own duty is preferable; following another's duty brings danger.

इति ते ज्ञानमाख्यातं गुह्याद्गुह्यतरं मया ।
विमृश्यैतदशेषेण यथेच्छसि तथा कुरु ॥

iti te jñānam ākhyātaṃ guhyād guhyataraṃ mayā
vimṛśyaitad aśeṣeṇa yathecchasi tathā kuru

Thus have I declared to you the knowledge more mysterious than any mystery. Ponder over it thoroughly, and then act as you like.
