Confused about caloric needs while on bed rest

[minimimis]

I hope someone can help because I'm impossibly confused about how many calories I should be eating.

I'm normally very active (lifting weights and biking) but recently and illness has left me on prolonged bed rest. I'm trying to do a little light light light activity but it isn't much.

Here are my stats:
Height- 5'' 3'
Weight: 112 lbs

I've found all sorts of mixed information on how many calories I should be taking in a day. The number has ranged from below 800 to around 1800. Needless to say I am a bit confused.

I hope someone is able to help clear this up ^^

Well, on a rest day for me, I mean, complete rest day, stuck to the bed all day long, I burn about 1700-1800, surprisingly. I wouldn't go below 1700, especially if your sick.
