Ahhhh, I need help

I don’t know what is wrong with my camera but it has been slowly dying I think 🙁 First it started erasing pictures after I took them, well actually it says file is corrupt so it’s blank, no pic. Then my youngest pulled it off my desk and broke off the door that houses the memory card. And now I’m trying to put the pictures onto my computer and it keeps saying error, unable to download pictures because they are the wrong format or something, I can’t remember lol I’m just worried about loosing all my pictures on there. I love my camera and I don’t know what I’d do without it. It has treated me well for 4 years and over 15,000 pictures later.
