try using a long scarf to help lift your leg. Just nestle the center of it it in the instep of your foot and lift upwards. For a while I had to step on the scarf then gently fall back onto my bed.
As far as getting down on the floor, make sure you are close to the couch then when finished sit upright, roll to the couch and using your good leg and arms pull yourself up. You can do this.

Neither can I get up from the floor so I had to do the exercises on my bed. It was not easy but it helped. 😇
