questions about spells

heyy so iv seen so much posts about love spells or bringing back an ex, or having an ex contact you, or having an ex suddently crawl back to you. but im wondering if any of these spells can be used to bring back an ex best friend? i dont want her romantically or anything like that because i see her as a sister. we had a messy friendship breakup but i need my sister back. is there any spells that will bring her back?
