Abithistavam is meant to remove fears and there are other stotras like Lakshmi Narasimha Karavalambam.
Notes:
There are many slokas to remove fear. Sri Vishnu Sahasranama stortram declares that it shall remove fears, reciting it shall be an atonement for our anger as well.
The following sloka can be chanted.
आपतामपहर्तारं दातारं सर्वसम्पदाम्।
लोकाभिरामं श्रीरामं भूयो-भूयो नमाम्यहम्॥
āpatāmapahartāraṁ dātāraṁ sarvasampadām |
lokābhirāmaṁ śrīrāmaṁ bhūyo-bhūyo namāmyaham ||
