Scammed by a person I was trying to help out

I know I’m gonna look stupid and I apologize for any person that I annoy by being so oblivious, trust me it’s harder to see the truth when you’re in the spur of the moment,so let’s get to it,I was contacted by a person for the pc I was trying to sell as I was facing financial issues,person asked me to drop off the pc at their house and that they’ll pay me in cash,when I got there they said they were sick offered me a percentage of the total agreed amount saying the rest would be for prescription drugs and that they were too sick to go to the ATM and that they would etransfer the rest they sent me a screenshot of the etransfer to a contact by my name but never showed themselves actually sending it to my email,I said I’ll wait in front of his house until I get it but my phone was dying and it was 10pm so I left,when I made it home it started making sense that I got scammed what can I do as rent is coming up and I got scammed out of what was supposed to be my rent money,I posted a picture of the scammer if anybody has had an encounter with this guy please let me know and what are my options.
