Feeling a bit down

Cant put my finger on how i feel tonight im feeling quite low dont know why ok maybe i do i have been trying to loose some weight for my holiday but it just isn't shifting i have tried smaller portions drinking loads of water ect but i still stay the same i know it's better than putting weight on but at the moment thats not how i feel.Got a few things on my mind at the moment we are due to go on holiday in 5 weeks time which im really looking forward to but my mum has to go into hospital the week before we go on holiday for a knee replacement so im worried about that although Charlie & i are going through on the tuesday night and will stay till sunday all being well mum should get home on the monday or tuesday.I know she wont be short of visitors but it doesn't stop me worrying it's bad enough we live 100 miles apart anyway but when im in majorca thats a different story.Mum keeps saying i have to go & enjoy my holiday which i will do my best to i will phone her every day the only thing is if she did have a problem she wont want me told about it.She had a DVT about 6 years ago and has been told this could come back again when she had the DVT she was in Benidorm with her sister but mum nearly died as the clot had broken up & had went to her heart & lungs she was only hours from death & was in intensive care for 2 weeks but she got better i think deep down this is whats worrying me.Hopefully i will feel fine again tomorrorw some how it helps when you put into words how your feeling but all the girls & Calv lift my spirits & make me laugh & seeing photo's of all the forum babies cheer me up no end with their cheeky big grins.
