Hello bwv998,
1)it still is the lack of sun. Typically, it should be more upright and firm and the leaves wide open, and leaf colors not too deep green. You can try and stake the plant, to help it.
2) Succulent roots do not like to be in too soggy soil, as with its stems and leaves, staying too wet, will invite fungal rotting. You may want to mix in pumice or perlite, and top dress with pumice or chicken grit to make it porous.
3) the cut-off top part will not die, callus the end and then stick it in barely moist media, wait patiently for about 4 to 6 weeks to form roots. It has enough sugar in its remaining stem and leaves to sustain the plant. Position them in part shade so it does not dry out too fast. It is summer time, so it is active growing time for it. Patience is your friend while you wait for it to root.
