Help! I just lost my pet

Hi! I have never done this before, but seriously now I am kind of depressed I had one little beautiful female guinea pig and she died some days ago, I just didn't see that coming, I seriously loved that guinea pig, she was my everything, she had a partner and died like 10 day after giving birth to 3 little guinea pigs, but everything I did was for her, I bought her a partber so she wouldn't be alone, I built her the biggest cage I could for her, and now she is gone. I have no idea what to do, I blame myself since I just thought she was kinda weird the night before she died, and I don't know what to do with the babies and her partner, I am just thinking about giving them all in adoption, I like them all but she was my everything. So just looking for advice, please
