Hydrangea Help!

Hydrangea Help!

Hi guys, A few weeks ago I got given a really nice bright blue Hydrangea as a gift. It was perfect when I got it and now... not so much. I waited for a few days to plant it, I found a spot, prepared the soil with some compost and fertiliser, cleared out any weeds and planted it. A few days later it was really droopy and not too healthy looking, so I watered it and it seemed to be happier. Now though: The flowers have gone a bit brown and every day when I come home from school it seems a bit droopy. After a shower of rain it picks up but that seems to be temporary. Not sure what to do now... should I move it? Is it too late? I'm in the UK for people wondering about climate. Its past the last frost and the weather is getting warmer.
