There were few questions in your original post- HERE - click me - you didn't really answer; mainly what were lowest temperatures your plant was in (freezing or not?). I am assuming you mean 11 - 13 degrees in Celsius (you didn't answer that question either). If that is the case, those are ok temps and will not kill your aloe. It should have no problem in temps as low as 4*C, perhaps even lower. But colder it is, potting mix should be drier.

Karen gave you good advice. On top of repotting into different/better mix, do not water until that mix is almost completely dry. To find out, use a wooden or bamboo skewer or chopstick, or even pencil. Stick it deep (3/4 deep is ok) inside of pot and leave in for a bit (I believe about 5 minutes is enough. But you can leave it longer). After, pull it out. If it is completely dry, you can water. If it is damp, or feels cold when touching your cheek (or top of your hand), and sometimes may have small soil particles sticking to it, do not water - there is still lots of moisture in the potting mix.

I believe - based on your description - that it is overwatered in that sand. Sooner you change it, better chance for plant.

When you take it out of pot, get rid of all sand from roots. Take a clear/sharp photo and post for us to see condition of roots.

Also that pot looks much too big for the plant

Thanks for repeating it, Andrea, perhaps you missed it, but I said exactly that in the last sentence of my paragraph above.

Lol yes you did

Yeah I got it out & stopped watering. Thank you all for helping me!!
