Beginner Gardening: Help with a suffering house plant., 0 by Williah

Hello,

I have a piri piri pepper plant that had been growing nicely and happily for over a year.

Suddenly 2 weeks ago the very-green leaves started shriveling and becoming brittle. I kept it with plenty of water and sunlight, just as I had before.

I think it may be a change in environment to very cold. I was working on my bedroom and slept in the living room for a week with ac. I moved it to the kitchen which is warmer. I don't know for sure it's the cold, though. I've included a picture.

Any help in finding out what's wrong AND saving the plant is greatly appreciated.

Will.
