Hello Angie :hug:
I'm so sorry you're feeling this bad right now. I think we've all been through days like this at some stage and can all feel for you. I don't really know what to say to help except that you have to rest as much as you can and leave the worrying until later. I know that's so easy for me to say and I know how hard it is to do but you really have to dish out loads of TLC to yourself.
I too suddenly got to a stage where smiling and pretending everything was alright just wasn't working for me. First off I realised that tiredness is my worst enemy. Thankfully once I get rid of pain I usually sleep well but well doesn't mean it is enough. My need for sleep often exceeds the "norm" and I HAVE to take naps or have long lie-ins in the morning. If I don't sleep, I feel terrible in every way.
The second thing is that you simply can't pretend it's OK all the time to everyone so I changed my attitude a little and now don't say "I'm fine" and smile sweetly if I'm not (I was finding that that smile was looking more like a grimace :lol

and I simply say "today's not a very good day". I don't wallow in it or make people uncomfortable and I quite quickly go on to talk about something else but it's funny, just the simple fact of acknowledging to someone else (even people who are just acquaintances or colleagues) that it's not a good day makes it easier for me to get through it.
Those are just a couple of things that help me. With time you will find what helps you most. I'm still learning on that score and I think that everyone here would agree that it's an ongoing process. Also, there will always be days when it all just seems a bit much but knowing that they will go and we'll feel brighter after helps us get through those days.
If you can't get an appointment with the rheumy, would your GP be able to help? I have found mine invaluable over the last few months and he has stepped in and really done a lot to help. I know I'm very lucky and that he is a real gem but even with him I used never to complain until I got to the stage where I realised I just couldn't do this alone.
huge hugs and hope you're feeling a lot brighter today :grouphug2:
