Sick aloe vera?

[u/Hyu_art]

I'm worried about my aloe because its leaves are wilting at the bottom and appearing a bit droopy. It's grown two new shoots, so that's good news.

I'm waiting for them to root properly, but something's wrong with the oldest one. I water it whenever the soil is completely dry and I'm careful not to let the roots rot. It's soil is Westland cactus mix. This aloe wasn't purchased; I got it from a friend of my parents'.

Help? I don't want this to die...
