I just bought it & it’s moist & not too sweet, not in a lot of sun.. I dnt understand.. I’m also, just learning about succulents in the house..

Droopy leaves can indicate too little water. Your image also shows brown tip of the leave which could be uneven watering or excess salts; over fertilizing or watering with conditioned water.

I believe your succulents and Jade plant may be overwatered. The soil looks dark and may not be draining properly.
