Kate, it sounds like you need a little bit of fun in your life right now, to get away from the mundane things that never go away. How long is it since you've been on a 'date' with your hubby? Just something simple, enough to give you that breathing space, even if it is just a walk, a movie, somewhere with lunch afterwards.
Plus don't start with 3 changes, start with one...sleep...i find if i get that one under control, the rest will follow because that fuzzy wuzzy brain will be gone and you will feel better in yourself and more able to tackle the next change. My sleep was crap till about 2 weeks ago when i gave my brain a severe talking to. Nothing much had caused it just a series of little things, 2 of them being our daughters purchasing their first homes just before Christmas and the little worries that come with it, helping them clean, set up, helping with purchases, answering endless questions, watching them stress over things whilst telling myself to stop stressing. So we shall be empty nesters at the end of this week, exciting but sad at the same time.
Don't ever feel guilty, Kate, not when you are doing so much for your family. And before you go to sleep tonight think of something that makes you smile. Love Cath xx
