Thank God, finally, my sister has contacted me. I waited for her to send a message coz I am worried about her. I was browsing and reading some articles in read.cash, when there's a notification that pops up on the screen. It was a notification from my messenger stating that someone wants to send me a message. I just ignored it at first because I am busy replying to the comments and after I am done with what I did, I scroll down the notify and I saw that it was a message request from my sister. I open it immediately then exchange chats with her. I am super happy right now
