I am hoping to get some help with my succulent. I recently bought a little pot full of a few different types of succulents. It was already looking a little bleak, but one of the succulents seems to be getting a lot worse. They started out looking like little green sticks, but now the tops are starting to turn brown and the leaves are shriveling and falling off. The leaves are very fragile now, and they can easily fall off if I gently brush it. I am not sure what type of succulent it is. My friend told me it might be Crassula Tetragona. I have also not had many succulents, so I am not sure if it looks like this because it needs more water or if it is something else. I have been watering it by soaking the soil and letting it dry, but I have watered it a couple times before it was dry because I was afraid that it was dying because it needed more water. I just checked the soil and it is still wet, so I am not sure what else I should do. Thank you so much for your help!! My dying succulent
