My Dad disappeared!!😭

Hello everyone..... I wasn't gonna post this but I need advice. On December 12th 2021 my dad called me stating that he need to have a major heart surgery that cost $78,428. I didn't want to loose my dad so I emptied my saving of $33,276 and sent it to him. I have 2 boys and I'm 5 wks pregnant.... I gave him everything... Now here it is 5 months later and my dad jumped off the face of the earth... Im struggling everyday to not be hurt but I feel like he took away from me and my kids. I called the cops and they informed me that I need something in writing but I wasn't thinking my dad would do this so I have no evidence... I feel stupid, lost, and hurt to the core. At this early stage of pregnancy I'm trying not to worry but What can i do?
