granjura Don't feel ashamed of feeling down and lethargic. It is understandable you are sad as you have lost your young friend but if you are feeling low and run down she would not want you to be ashamed about it, she would just want you to get better and to look after yourself so this is what you should do. Get plenty of rest and sleep, eat some good food and do something nice for yourself. Take some honey and lemon to boost your immune system. The more you get better now, the more you can be there for her lovely girls.
I am not sad, I have a house move to look forward to, new walls to decorate and rooms to kit out so lots of excitement, but even this can take energy out of me so it's being run down and if I do too much then my energy becomes depleted and I get ill. So I've slept most of the weekend, even now I've just had a sleep after getting up earlier. I've had honey and lemon and buttercup syrup coz my chest felt sore. My throat tightens for some reason when I do too much, not sure what that is, it's happened now for 17 years. I just have to take my time in the packing up, very frustrating to want to be getting on with it when the body is objecting.
