Sparkles - sorry to hear you are feeling down today
, - but this is the very place to talk about it - we've all been there. It is totally normal to be feeling down, with what you are going through at the moment. Do come on here and chat about it if it helps.
It might also be worth having a chat to your GP, to see what is available to get you through the difficult patch. Sorry to hear your DH is suffering from depression, - it is a horrible thing to cope with. I completely sympathise with the 'just get through the day' feelings, you are in a sort of limbo at the moment waiting for your a DX, and the uncertainty is very hard to deal with.
I know its a cliche, but just try to focus on one day at a time, be kind to yourself when you are feeling low, and when you have more energy, trying to get a bit of fresh air really does help. The rash will also be bringing you down, so hoping that starts clearing soon. Hang on in there, we are all here for you
