how i found you

Hi my name is Sarah and I'm a passionate but novice gardener and a newby to forum's, so please be patient with any mistakes I may make, either in the garden, or any protocol I may not follow correctly on the forum!
I found you whilst searching desperately for help on what ailment my Butia Capitata is suffering from. I used the Yahoo search engine and came across gardeners corner and after reading many questions about other peoples plant concerns and desperately needing advise about my much loved jelly palm, i decided to overcome my fear of forums and technology, and register, hence this post.
So here goes..... I live in the South west of England and have had my Butia Capitata for 3 years, I bought a relatively mature plant as i wanted to use it as a specimen plant in my newly renovated garden,( project is well underway but still have lots to do), it was happily living in a very large pot on my patio for two years and last summer we moved it into its final home in a large planter with drainage built in, i also have a mature Chamareops Humilis in an identical planter, both built and designed to take these specific palms. Even though we didn't experience the worst of the winter down here in the south, we did have a big freeze prior to Xmas and snow for about 10 days in January, however although some of the new fronds from last years growth turned brown both species seemed unharmed. However just last night, with the essential glass of wine in one hand and strolling around the garden checking out all the new growth i was horrified to find that all the fronds on the jelly palm seemd to have closed up and the tips appear brown, it looks very sad and stressed, my first thoughts were that it may need water, but the soil was not excessively dry, i did however give it a good soaking in the hope that i would wake up and find it had recovered, unfortuantely, this evening, with a second glass of wine in hand i discovered there has been no such recovery and the soil is still slightly damp.
I guess my question to the forum would be, do you think my jelly palm is thirsty and am i expecting it to recover too quickly? If it was thirsty will it recover? Or is it something more sinister and if so what can i do, if anything, to help it recover.
Wow what an essay, hope your still with me. Thanks for listening. PS the Chamareops appears healthy?
