I have an Aloe Vera plant that's around 4 years + old (Can't remember when I got it) and is kept indoors. (I live in England where it rains most of the time!!!) It's near a South facing window. It has a long 'trunk' and is propped up. Although all the leaves are green and full of gel they keep thinning and bending at the trunk. My plant now has droopy sad looking leaves.
It's still producing new growth and has an offspring at the bottom. It fell over the other day and looks even sadder now

Where did it all go wrong? Is there anything I can do? Can I cut the trunk and plant it? Will it grow roots if I do?
Desperately want to save it.
